"Atheists, isn't the simple fact that the bible was written by many men and agress with itself proof of God?"
No. Why should it be?
"As in, all other religions were made by one man. Buddha, Confucius, Muhammed, even some books of the Pagans, like the Metamorphosiswas written by one man. Yet the bible was written by many men, and yet they all agree with each other, because of course it's from G-d."
Except that they don't all agree with one another. Pretty much the entire OT is rendered null and void by the NT, at least as far as the character of your god is concerned and what is, and is not, "sinful".
Other than that, why is it surprising that people with access to the previous writings would, themselves, write something in agreement with what was previously written? It's like a collaborative novel where each author writes a chapter. Obviously each successive author has access to the previous chapters so it's not surprising that their own chapter agrees with the previous chapters.
"So isn't that proof, because while other religions agree only because one man wrote it, the bible agree and many men wrote it. :)"
Who, once again, all had access to the previous writings. Wow. Amazing that they agree with each other on the basics.
"well I should add, that they more or less agree. :)"
Ah, so you're not completely unaware that your Babble contradicts itself left and right. There may be hope for you yet.
