The Bible is a scripture depicting "human" history to an extent, and laying out the guildliens needed to have a functional society. If they had garbled the bible with all the facts of earths history it would've taken away from the power of the book.
Scientists have not made life out of nothing. They've tried. They can't do it and it hasn't happend since.
They said the whole world flooded and i wouldn't be suprised if there was a massive flood, but ever notice how no other ancient scriptures have a reference to a great world flood, but do have lots of references to a great ancient flood. The black sea ( or balitic i don't remeber which ) used to be a valley or something like that
Remeber everything in ancient times was centralized in that area of the world. So noah could've made a boat and put every animial that he knew of on it. Or it could just be a fable, but animals in every other part of the world wouldn't've been affected, but still it would've been like flooding texas.
I could go into further depth about this as there's been documentation about it. Noahs warnings came in the form of waves and things i believe and the tide would've acounted for this as there was cracks in some sea wall or something.
Regardless there may or may not be a god, and the bible is factually based, but it should be seen for what it is and not what it isn't. It is the single greatest testament to human survival as a communtiy every produced.
