A loaded up Kindle with a solar recharger and a spare battery or ten. Small took like. 9mm with lots of ammo, knife, fire starting kits. Plastic tarps. Toothbrushes. Change of clothes. And a towel.
No toothpaste?
TP was a good one also. d’oh.
You’d run out of both, so getting used to it right away is best. Not waste space for the ammo reloader stuff. Saw and a file too.
Well, the only thing it would be good for would be to smash the natives over the head. What were you planning on using it for?
Power Point presentations!
Do we need nasally inserted fire? What color should the wheel be?
Yeah right. Get used to tooth decay or gum disease etc? I’ll pass. Plus toothpaste doesn’t take up much space. The TP does though and I can see getting by with broad leaves eventually.
ecch. So glad I wasn’t born back then.
So you’re opting for the “evil God” idea. Well it might have its merits…
Lascaux France. I would my own cave painting of a B-17 surrounded by TIE fighters.
Probably some Ninjas too.
Just kibbitzing, I am an insulin dependent diabetic that needs 4 different BP meds to control my malignant hypertension so I would basically drop dead fairly soon after going through the gate …
Seedwise you would be smart to have about half a dozen potatoes of 2 or 3 different kinds [they multiply fairly nicely from spud form, so if you plant the cut up potatoes and then keep replanting without eating them for about 5 years you can end p with a lovely large food supply that is very nutritious. Hm, one of the better disease resistant forms of wheat, the one that was developed to tolerate dry and cold so there is a decent chance it will survive a mini ice age. New world trilogy - corn, beans and tomatoes would also be good - in combination they are a fairly complete protein source. Toss in a handfull of assorted modern seed packets from agway , and add a dozen or so seeds from a marijuana seed bank - half dozen each of a landrace afghan indica and a landrace south american sativa to cover both bases. [the different chemical profiles mean that the 2 different types of weed do slightly different medical effects.] Pack the seeds in a camp pot. I would also like a pot to boil waterin for drinking. If I could manage to get some coffee, I would be all set 
I would think a fairly dependable revolver, I have a nice ruger service 6, and 8 or 10 boxes of ammo. Only for use in an absolute emergency. A pair of seriously good knives - one of the ww1 trench knives that combines brass knuckles as the hilt and one good cooking knife, and a whetstone. One shovel head, one hatchet head, one ax head, one hoe head, one adze head. Handles can be made there. One handcrank flashlight, and a box of generic cigarette lighters.
Toss in a selection of gold and silver in the form of jewelry - chains, rings and bracelets for monetary type barter, a pound of peppercorns, a pound of salt, and a pound of real cinnamon bark, and a pound of sugar. Dressed properly, I could be a trader though as a woman I would be in real danger of being taken and sold into slavery. Do we speak the local language or do we need some sort of dictionary?
I would like to be located somewhere in europe with soft limestone or sandstone cliffs, a hobbit hole if dug properly is dry and comfortable, and tends to be a reasonable temperature. I would prefer to be somewhere somewhat out of the way, in a temperate area that gets down to maybe 0 F at the lowest, and doesn’t get much hotter than mid 80s. A good water source, reasonably fertile land with mixed hard and soft woods.
Interesting responses.
I don’t think much of demonstrating god-like powers or magic. It’s very easy to demonstrate that you are not a god. For instance, gods don’t bleed to death or scream in pain when you stick things in them. Even ordinary magical items like a Bic lighter are going to be a problem because you can only carry so many with you, and eventually they run out. A bunch of magnesium spark igniters would be useful and not overly magical.
Firearms would be useful short term, but your chance of finding more ammunition are pretty slim. But if you are going for the approach of surviving on your own, the short term utility of a gun for hunting and defense may be worth it. I’d consider a simple black powder musket though, because you have some chance of making gun powder to keep using it. Instead of a firearm, I’d bring a cross-bow (or regular bow if you have the skill). You can always make more bolts or arrows, the heads are easier to recover then bullets, and you can bring extra heads with you.
The fertilized egg idea is a good one. You can bring a couple of dozen, and even a substantial amount of chicken wire to get yourself a little breeding population going while you build a larger coop. A never ending supply of eggs and a few whole chickens a year are going to make your life much easier, otherwise you’ll be spending most of your time hunting and gathering, often with little success. Seeds are also small, and give you some more food variety. I’d definitely go for quantity producing fruit like watermelons and pumpkins, and maybe corn. I’d bring a lot of fish hooks too, they’re small, and about a mile of high quality fishing line.
Some emergency food would be useful also. I’d bring granola bars, heavily soaked in honey, and some salt and spices just to add a little flavor to whatever foods I can find locally.
Toolwise, a couple of hefty bow saw blades that can last through many sharpenings will be invaluable. I’d bring several hatchet heads and one handle. The hatchet heads would vary in shape to be useful for different wood working tasks. It’s easy to make handles once I get there. One large axe head might be useful. I’d bring a variety of knife blades in different sizes, and again one handle. There should be one large heavy knife, large enough to use as a weapon, and heavy enough to pound on the back to use as a fro. I might bring a couple of auger bits (1/4" and 1/2") and a piece of steel I could make a T-handle for them with. I’d several yards of stainless steel wire, and a lot of kevlar string. Whatever space is left in the duffle bag at the end I’d fill with copper.
Antibiotics, some aspirin, and some heavy duty painkillers would be helpful. I’d also bring in powder form the equivalent of Pepto-Bismol, and something like Metamucil. Getting used to micro-organisms could take a while. And some amphetamines.
Cheap costume jewelry will make good trading stock, and some small pieces of gold will also be useful. Small knife blades would be good for trade also.
Most of the small items can be stuffed inside other things, so the fishing line can wrapped around a thin plastic tube and lots of things stuffed in the tube. 50 feet of chicken wire would be rolled into a large cylinder the diameter of the duffle bag, with pills and and jewelry stuffed into the spaces, and all the large things going inside. The cross bow may be the largest object there. I’d go for something that can be carried in parts and assembled there, with a stock I can make out of wood. Packed right, a duffle bag can carry a lot of stuff.
Oh yeah, I’d also bring a lot plastic bags. Small ones and large ones. Some Zip-Lock type also, and a several square yards of black builders poly too. And the largest plastic bucket that would fit inside the duffle bag.
If I went out to trade (personally I’d rather do that than hunt and gather), I’d bury almost all my stuff in various out of the way places before I went to meet anybody, only carrying my large knife, some costume jewelry, a couple of granola bars, and hide a few bits of gold among my clothes. I could easily use my woodworking skills to make some things to trade also.
Communication would be important. I’ve been pretty good at using sign language to communicate before, so this may not be too hard to get started. When you meet someone you start with an elaborate salaam as a sign of respect, and to get attention, then do the “Me Tarzan, you Jane” act to get names. Give out a few trinkets and make a big deal about shaking hands and sharing the granola bars. Then I’d try to act out the bear and rabbit joke.
Toilet paper and other niceties would just take up space in the duffle bag, and not last long, so I would forgo them.
Of course all of this presumes I was somewhat younger and had the energy needed to work and travel, and no health issues to be concerned with. In my present state, I’d be better off just loading up lots of drugs, alcohol, munchies and porn. At least my last few days alive would be enjoyable that way.
Wow, great responses!
In a video game sort of sense, I wonder how it might be possible to change history for the better… could I forge a great, but fundamentally just, empire? Could I put a serious dent in magical thinking (which was probably all thinking that far back)? Could I leave a legacy that would improve the human condition? What could conceivably be accomplished?
I have been working on my equipment list and plans for a few days now. I have a singular goal to stop the Roman Empire before it expands too far. Will you modify the OP and let me land in southern Germany about 250 bce? Still pre history. Fun OP
CAPT
Thanks 
Not sure if I have the power to “modify” the original post, but knock yourself out 
Or, if you like, start a new thread with your scenario- it sounds fun too.
Introducing technology will be easier than changing attitudes. The advance of technology will tend to reduce magical thinking over time. A fundamentally just empire? Tough challenge. The powers that be will assume they have that already, and not see an advantage in changing. The powers that aren’t are unlikely to be interested. You could try the Jesus thing, but that didn’t work out to well for the last guy who tried it. Though you could leave a nice legacy that way. Make sure to get some literate groupies.
Teutoburgerwald … was that your doing? You sly dog!
But I think where (when) I’m going, there are no powers that be. There were almost certainly societies of some sort before recorded history, but were there any political empires, with power of more than their immediate little bit of territory?
I don’t really know, but you’re in a time just before the Bronze Age. I’d think substantial trading over long distances was already happening, as well as mining. (Aren’t flint mines older than that?) There may have been substantial communities in existence with established authorities. If not, the task is even harder. You would have to be a great leader of men that can that can organize people to be more productive and allow a percentage of the population to form an army, which then has to be trained, and used to take land and power. Remember, it’s my contention that too much magical ability will end up with you failing the witch test, so you’ll need some real talent to become the head honcho where you end up.
If I get bored I can watch I Love Lucy.
Nah I will honor the OP.
Drop me off in Scandinavia, at the beginning of the bronze age, my people will make it to southern Germany in plenty of time. I will not seek to lead, I am an Ambassador from the far east and I have come to benefit them. I need 2 years to prepare

Learning as much as I can about the language so I can communicate a little bit
The plan
I will teach my proto Germanic hosts Iron working in the early bronze age so they have a technical leg up when they meet the Romans in 2000 years time, they can crush them with Steel. My hoped for result Roman Christianity never dominates Europe and an age of reason will be born, I doubt it will work
That is all
CAPT
Nice work Capt. 
But weren’t the proto Germans the only ones the Romans DIDN’T defeat? I’m not up on my history for that period.
How long can we plan beforehand? I’d want to learn the bow and arrow really well. And how to light fire by banging rocks together. If I met natives I would teach them writing and/or the sign language alphabet and try out words like “mama” and “milk” to see if those words are really that old. I would want my dog with me so they can “ooh” and “ahh” over the weird looking wolf with no testicles who can run like a deer (and looks like one from a distance). Unless they already have dogs at that point. But I’d still want the dog there. I would not bring seeds; that would take too long. I’d watch what they forage for and show them they can just uproot the whole plant and transplant it nearby. I’d let them marvel at my whiter than porcelain skin (though that obviously won’t last and I actually tan pretty well). Perhaps they’d like my green eyes. I would try to see if there are any neanderthal/cromagnon hybrids among them.
And then I’d probably give them smallpox or polio and kill them all off. Oops.
