You certainly did, if God didn't make it then something else did, and I assume you have a theory about what that is. I suppose you could prescribe to the steady state theory, but that seems a little dated.
The Big Bang theory everyone loves, offers no explanation of where the original matter, that became the Big Bang, came from.
I don't even say "God didn't do it" (really, who the hell am I to tell anyone that their God doesn't exist just because I don't share their belief? Too bad some believers aren't so accomodating)....only that the empirical evidence that "your God did it" is limited to......a book.......I'll also add the bit of humor that if God created us in "His image".........He is one UGLY God, because Homo habilis was one UGLY dude.
I am never on an anti-religious crusade (heck....been to religious worships more than some that ARE "religious") and only want your religion to be kept out of a science room.....period....it does not belong in a science room. Teach it in any one of the religious studies classes that were available to me.
