Nope, sorry, that's not true.
God presented himself to Moses, and spoke to others through angels, etc.
Nope, sorry, wrong again. The Bible is basically a history book inspired by actually events, except for the book of Revelations which is a foretelling of the future.
You know NOTHING of what the the writers of the Bible knew, or you wouldn't here proclaiming to be an atheist, and theologians can only give you their opinion.
