My problem with the 7 day creationism argument is ... why 7 days?
Like, if you're omnipotent, surely you don't need to work to a schedule. And what's with the rest? An omnipotent God gets tired?
Either God isn't as powerful as he'd like people to believe or he's lazy. Or both.
That's actually an interesting question. Why indeed? My bet is that for the original creators of the myth, all those thousands of thousands of years ago, the answer was probably obvious in a way that's been forgotten. Maybe their creator god wasn't omnipotent. Maybe it's religiously symbolic in some way. Maybe there's some narrative element that we're not aware of, because I agree with you - it doesn't make much sense.
There are actually some Christians who have tried to explain it as symbolic in a way that can be combined with what we now know of how the Earth was formed. They would argue that it actually refers to epochs, not days (although they would relatively speaking be to God what days is to a human), that it reflects how God formed the Earth over a very long time and through the now known mechanisms of geology and evolution and that the rest period explains why God seems absent now.
Personally, I think it's all mythical. Still, it's interesting to think about why it's written the way it is.
Abiogenesis has a ways to go before it actually answers his questions.
True, but it makes more sense than "God did it" based on what we know about the world. And the fact that our knowledge is incomplete doesn't logically support creationism in any way.
