I’m a hard-core apatheist. God may or may not exist, and my opinion on the matter probably doesn’t matter too much to him if he does exist. He’s probably got bigger things on his mind.
I believe the man that performed that first experiment with the primordial goop and electricity was Steve Moore or Steve Miller or something like that. He put in a lot of carbon compounds, like carbon dioxide, a lot of nitrogen, some metals, some clay, stirred it up, and ran a bolt of electricity through it. In his own words, paraphrased, it turned from nearly colorless to bright red, with lots of solids and such precipitating, very dramatic. Others have tried to duplicate his experiment. They didn’t have the same drama to their results, but their results were similar. They formed a lot of nucleic acids, simple sugars, and amino acids (the one the precursor to RNA and DNA, the second to complex sugars, the other the building blocks of proteins, the three basic building blocks of life, I believe).
The Earth was, a few billion years ago, a big hot lump of clay with a lot of carbon and nitrogen gases swirling around, with oxygen locked up in both (CO2, NO2, N2O, N2O2, N2O4, CO, etc). The clay would’ve had a lot of metals and metal oxides and such in it, all wonderful catalysts.
That is, at least, the theory, I think. 
As for the “chances just being too small without an organizer” and “the rules are just too convenient for us” and “the earth is perfectly situated”, I don’t buy those. When it comes right down to it, if circumstances didn’t favor us being here, we wouldn’t be here. As it is, since we’re here, we shouldn’t be too surprised that they DO favor us.
However, what I think may be a good argument for the existence of an organizing being, or at least some force to combat entropy, is, I believe, a force that tends to organize things. I think I read in James Gleick’s Chaos an experiment. Or maybe it was a book on AI or Artificial Life. Either way. A man set up a field of 100 by 100 lights (ten thousand lights, a very large number). He had a large number of cards that would determine the rules (from all the boolean operations) wether each light would be on or off, based on if its neighbor’s were on or off. This was in the day of punch card programming, so it was easy to randomize these rules. He shuffled the cards. In theory, one could see 2^10,000 combinations of lights on/off before the system would repeat. However, every time he did it, it went through about 14 or 15 iterations… Make of that what you will. Is there an anti-entropy? A god, perhaps? I dunno. I’m just interested in passing my finals, doing the same for another 2.5 years, getting married, moving to the suburbs, having 2.5 children and 1.3 dogs, and fading into blissful anonymity.
Yes I’ve been up all night and have had a bit of coffee. I should really get back to studying.
