So please, put away your flat, 6000 years old Earth, the Great Flood and that 'a man created from dirt, a woman from a rib bone' nonsense to rest.
Since there is nothing but theory that contradicts the Bible record, and since theory is not known to be fact, go with the Bible record rather than the unknown.

Appealing to biblical authority with people who don't accept the bible as authoritative is pretty silly. It's the worst sort of pointless circular logic.
The problem with this is that it is actually known

90% of the stuff in the Bible is plainly untrue, it is not methaporicaly said, it is not an allegory
It's just stuff that isn't true
The whole Old Testament was written prior to 2400 years ago. The fact of the age of the Dead Sea Scrolls, which are from about 400 B.C., shows that the O.T. is similar today, to what it was back then. Using scientific extrapolation, odds are that the O.T. is similar all the way back to the times that each book was written. Yet, there is a symmetry in the whole thing that makes it look like it was written at the same time, even though it was written over hundreds of years.
The point is, for this to have happened, means that there was a Guide to making it happen - God. In addition, The people who wrote it and copied it so accurately shows that it was real enough so that they understood the importance of it.
The Bible is true. If it weren't, it would have perished long ago, and if we had any copies at all, they would be museum pieces. Rather, because of the greatness of the Bible, the greatest nations on earth have become great through following it. God has made them great because they respected Him enough to hold His Word important and sacred in their hearts.
