Why don't you believe in God?

i have a pergunta 4 u....y r u even looking up this if u DO believe in god?? and the videos, though funny, explain my veiws. they just, u know, put a spin on it and make it funny! though, u probably wouldn't like it.
one of the 10 comandments is basicly saying not 2 kill.
but if u pay attention then u know that god is the leading cause of death! through out time the bloodiest battles were all fought and people were killed basicly because god said it was a good idea!
as 4 how the world was made, well science has covered that department pretty well, hasn't it?
