Personally, I
do believe in evolution. I have all the 'proof' I need when I look at the world around me, the way things grow and change. And really, that is all evolution means-- change. Nothing is static. Everything is constantly in motion, even the molecular structure of a rock never stands still. Given enough time, things can change so much that you might not recognize them anymore.
Now, I'm not saying that we came from monkeys, per se, at least not any that still exist... but it seems foolish to think that humans simply started appearing out of nowhere. After all, we humans have to eat, breath, sleep, sh!t, fvck and die like everything else on this planet. How are we really so different?
After I've said all that, I will state that I believe in the spiritual element as well. I see no reason why I couldn't have evolved from a 'simpler' life form and still have a soul.
If you really believe in a god who is infinite and immortal and all knowing, why would it be such a big deal for him (or her, or 'it') just to sit and wait for the test results of his grand experiment called "life" even if it took a billion years (not that I believe thats what life is about, it's just an example to all of the bible thumpers out there in don juan land)?
Think about it.
