According to the biblical witness the human mind (in its unregenerate state) is foolish and God excluding. And this darkened intellect will generally interpret evidence of origins in a God excluding way. They claim to be objective, but this of course is impossible. We all begin with assumptions.

One example of this concerns so called transitional fossils. Creature A has specific features. Creature B has some of the same characteristics as creature A with a new feature or two. Creature C has some features of both with a new feature or two. The assumption is now made that creature B was a transition between A and C. And that they are all related. But this is pure assumption. We do not know if A was an actual ancestor to B and C. Heck we can not even know if A had any offspring that lived.

Now at times we will find A in lower strata than we find either B or C. So we assume that A is older. A may be older but again that does not prove physical ancestry. And often we will find both A and B or B and C in the same strata.

So we are left with induction and interpretation. And the carnal mind will do all it can to exclude God from the process; they will interpret the evidence in a God dishonoring way.
