“Now if we can come to an understanding about the rest of the bible being symbolic and full of metaphors, we’ll be getting somewhere.”
References to the four corners of the earth and sunrise and so forth are in poetic and prophetic books. References to six-day creation are in historical narratives right in there with the genealogies, the troop movements, and all the literal stuff. Further, references to six day creation are referred to as literal by Moses, Jesus, Paul, and others. They are never referred to as being metaphorical.
As for grant money to pursue an investigation of odd skulls whose DNA does not match our own, I doubt I could get a grant. Firstly, I am not a degreed scientist and doubt I ever will be. Secondly, those who believe God created the world don’t get grants from secular or governmental institutions. We are not politically correct.
