Logical Deduction: Every planet and moon and star that we can see clearly enough to see that it is round IS round. Ergo, the earth must be round.
Empirical Evidence: Satellites put into orbit CIRCLE the earth. Humans put into orbit actually SEE a round earth below them.
There are other more scientific means, but the above should be simple enough for even the … ah … “less knowledgeable among us” to understand.
Makes no difference; they’d just wave it off with some sort of verbal diarrhea. There is now a famous YouTube posting where some flerthers spend $20,000 on a laser gyro to <i>prove</i> for once and for all the Earth does not move. They plugged it in and whaddaya know, it drifted 15-degrees an hour. They immediately concluded they’d been wasting years of their lives backing the wrong hypothesis and apologized to all concerned.
And if you believe that, I have a bridge for sale.
Damn, you’ve just ruined my favourite bit of folk humour. Twenty years ago, in the University of Toronto’s Department of Computer Science, the following three messages were scrawled on a soft drink vending machine, next to the usual warning pictograph of the machine falling on a hapless customer:

Flat-earthers already dismiss every other piece of evidence that conflicts with their flat-earth model. Humans who were “put into orbit” never orbited a damn thing, they’re part of the conspiracy to suppress the truth, namely that the earth is flat. The flat earth model is infallible; if any observation (or more usually, any report of an observation) conflicts with that model, the conflict is reconciled by dismissing the observation as flawed (or dismissing the report of an observation as a lie).
But the Earth is not like those other things. The Earth is the foundation of all creation. Those others are things that God put in the sky.
Like MachineElf pointed out, there were never humans, or any man-made objects, in orbit. Those are NASA lies.
Note: I am not making these arguments, I’m just listing the responses that the Flat Earthers would give.
I’m actually almost a little surprised that the Flat Earthers do say objects like the moon and the sun and planets are spheres. I mean, why not double down there. Sure, they’re round, but, like the earth, they are flat! Flat earthers don’t deny the planet is round: it’s just not spherical.
Yet, it does seem they admit the sun and moon and planets and possibly even father off stars are spheres, but the earth itself is flat. I assume they just found there were too many things to explain away there, and it’s easier just to accept the spherical nature of extra terrestrial objects and just concentrate on the flat nature of the earth.
Naivete is so refreshing.

Oh, I’m just going by what’s on the official “Flat Earth Society” web page. Assuming there is something as an “official” Flat Earther. The fact there are competing theories is actually a bit of a relief. It just seems to be more consistent with the general nuttiness than admitting the moons and suns are spheroid, while only the earth is flat.
Is it Eric Dubay’s Flat Earth Society? If not then you looking at the controlled opposition, paid shill, and specifically in the case of Dubay, Jew run fake Flat Earth Society.

For a simple test, I would suggest to someone living in a city to picture another city that would take at least three hours to drive to, i.e. ~150 miles or ~240km away. Then on a clear day, climb to the top of the tallest building in your city. Can you see the other city? If the Earth was flat, you should be able to. If you prefer, do the climb at night. Can you see the lights of the other city? If the Earth was flat, you should be able to.

Y’know, if you move the goalposts far enough, they disappear over the horizon… 
There comes a point where you realize that you know too much about what stupid people think, at that point you should reflect on the poor life choices that brought you to said point.
Personally, I blame my YouTube addiction for making me hit rock bottom.

I dunno. Sometimes it’s pleasant to point and laugh once in a while. Or even occasionally, punch in the mouth.
Or if a fata morgana is active at that moment.
Even the geocentric model requires the Sun to pass under the “Turtle” every night…
Of course Terra is flat. Colombo set sail for the Americas with four ships. The Santa Cruz sailed off the edge. It was later spotted by a UFO observer who mistook it for a Zeta Reticulan probe. Silly man. :smack:
According to Robert Anton Wilson IIRC a competent conspiracy distracts attention from its existence with diversions and alarums. We’ve not seen much news lately of UFOs, crop circles, Area 51 and Dulce, Zeta Reticulans, alien anal implants, etc. Flat Earthers are the distraction. No, don’t bother looking for the Nazi Antarctic flying-saucer base.
There’s more than one geocentric “model”. A common one used by these bozos is where the Sun circles above the flat Earth with Magical Light Properties making sure just the right areas are light and dark. There’s a video link in scr’s post above showing one of these “models”.
The bizarreness of this “model” is amazing. Somehow this Magic Light Property works uniformly North and South of the Equator despite the North Pole being center of things. E.g., at the December Solstice at noon in SE Asia, the light from the Sun is blocked over the N. Pole and much of the W. hemisphere, yet the regions in Antarctica below the Antarctic peninsula are somehow lit despite being on the other side of the dark area.
I had a long running debate with a flat earther who claimed that the flat earth model was simple and observable while the heliocentric model was overly complex. He believes in the UN flag model. I took him up on that doing the math and found out that the flat earth model he proposed is extremely complex what one has to do to get it to work with observations. Things like the sun is always above your head though there are times you can’t see it, buuuuuuttttt refraction, but that would bend light in the opposite direction then what you need and the opposite direction that what one can observe. Also he believes that no one has really seen sunset or sunrise at the horizon, but it is just a trick of the mind from so many images we have been shown, so that one is out. And how the angle of the sun overhead changes as a constant angular rate, which does not happen with a overhead sun.
Then he admits that no one really knows the true model of the flat earth and people are just making assumptions since the powers that be (who do know what FE is like), don’t allow people to study it.
The best I could come up with is to have the firmament (Racca - that solid dome that protests us from what is outside) the flat earth if a very masterfully crafted lense that would refract the sun and moon making them appear and disappear and even could give the illusion of sunset/rise, though I’m not sure of eclipse. Also we could replace the solid structure of it with a liquid (one biblical description describes it as molten glass), so that could allow currents in it and ‘spaceflight’ so satellites we can see are things we got into that molten liquid level and is just sailing on the currents.
We also would need God to have created some type of spacetime warp that makes distances shorter in the southern hemisphere, as he claimed that no long distance flights exist in the southern hemisphere without traveling to the northern hemisphere but there are and ones that go further south to get around the globe and you can book and travel on those flights. So the spacetime warp was needed to account for the flight times which without the warp would require the flights to travel supersonic.
It was quite interesting creating a flat earth which agrees with what is observable, but unlike what he said it certainly is not simple…
