First!
Religion was created as a means to control otherwise barbaric people and scare them into behaving. Now that we have society/laws/government/rules does religion have any place in the 21st century? I think not.
Also, am I the only one bugged by the fact that almost all 'great tales' from any religion all seem so unrealistic and impossible? How is believing in those tales any different than believing in santa/easter bunny/etc ?
Also, some interesting experiments:
Miller-Urey experiment
http://en.wikipedia.org/wiki/Miller%...rey_experiment
Provides an alternative to a 'mighty being' creating every living thing on the planet. Basically a bunch of biomolecules floating around, zapped by lightning --> organisms formed.
Evolution took place with those organisms --> HUMANS
