You are partially correct. And took my statement out of context. The [i]effect[/i] of gravity is obvious and without a doubt there. How it works...is the theory. And believing in evolution would contradict the Bible in that it says in Genesis that God created animals along with humans. As far as why the bible is true, I have done what you likely have done and weighed both possible realms of possibility. Both that if there is a god and if there wasn't. I've studied the Bible ([i]The New World Translation[/i]) and everything matches up accordingly. For me, it seems more logical that there is a higher being than us than to believe we are here by chance and serve no purpose.
