It's false to think only civilizations with a written language can be educated, did you overlooked passing information by word of mouth.

Understanding a metaphor means that you are qualified to comment on the creation of the universe? It appears that I've been wasting my life. I could have been a astrophycisist years ago.

"Azeusism, or not believing in Zeus, has been the cause of almost every single major atrocity of the past several thousand years."

I've recently come across this, and I think it's perhaps the greatest response to people who claim "atheists have killed just as many people as theists" or even "atheists are immoral".

I don't believe in God because I don't know what it is. I've never seen a definition of God that I believed in, so I can call myself an atheist.

Also don't believe in any other deities/creators/miracles/souls/etc,etc,etc. Why? Because I have no reason to believe in them. Occam's Razor.
