i have a question for the OP...
is the thought of a god really rational? or any more rational than the conclusion you mentioned in the first post?
not trying to change your beliefs or preach or anything, but alot of the stories told by the bible are EXTREMELY irrational and far-fetched, with the only explanation being that it is "gods work". that essentialy explains an impossible series of events by using an opinion, or an un-proven and impossible to prove basis, which SCIENTIFICALLY makes the answer to that question invalid. its very similar to someone asking "why is an e30 better than an e36?" with the answer being "because i like them better". whether people want to believe it or not, science is the basis of all things and the only way to 100% prove anything, yet theres no scientific proof or evidence that god does or doesnt exist.
i believe in organized religion as a good thing to some, but a horrible and ignorant crutch to others. there are many MANY people that let their religions influence them in a good way, but too many others who use it to discriminate, belittle, and hurt others. in my opinion, there is no such thing as a wrong or right religion, but there is people out there who act in ways that the founders and fathers of the churches etc. never EVER intended. the bible, koran, etc are all VERY similar and are more like stories with morals that have alot to teach about humanity and that have alot to teach to people, until they are misconstrued into negative things.
