Only fools believe the Bible? Doesn't help your argument by condemning the majority of this country.
Only fools believe in litteral interpretations of Genesis.
We've been through this on other threads, but here's the short story.
There are two entirely different creation stories in Genesis. Gen 1:1 and Gen 2:4. They have different sequences and timing periods. Arguments that Gen 2:4 is a clarification of Gen 1:1 rather than a separate and different story, can be, and have been debated.
There wasnt' enough room in the Ark for all the animals.
There is no geologic history of a worldwide flood.
The mitocondrial DNA does not show all species to have descended from common ancestors that survived the Ark.
You should take Genesis for what it is. A collection of oral stories compiled by Moses. Attempting to translate it litterally and reconcile it with science is impossible, and only attempted by fools.
