Odds are not incomprehensible. They can be expressed in finite numbers, using exponents. Not incomprehensible. Just high. But that we're here is just evidence that we're here. Sure, the odds were against it, but look around the universe and you see that most of it doesn't have life. That life is alive WHERE IT'S ALIVE is not startling. It's a 1:1 chance. So, no, I don't go "Wow, I'm so glad that I wasn't born in the heart of a sun or in outer space b/c I'd have it rough". So then we come to the "hey, atheists, do you know everything ?" part of the question. No. We don't. We just don't make up answers and say they're true. Especially answers that are logically impossible (such as an omnipotent entity who loves us. Look around. Notice the total lack of suffering ? yeah, I didn't notice it either.Notice the constant blissed out look on the faces of every human ? Yeah, I didn't see it either.) As for whether or not there will be a 'big crunch'. Hey, I don't know and I don't see what it has to do with your argument. Yeah, universal heat death is real scary. And ? Something blows your mind. Fine. That happens. And ? Oh, it blows your mind even more that evolution could be true. Well, it must be a magical sky fairy then. Yeah, that makes more sense. Oh, extra vowels and caps lock. Well, can't argue with that.
