Here is a post from David F. Reagan's Article: To Gap or Not to Gap:
Objection Three: The Gap is an Accommodation to Godless Geology
I admit that many of the early proponents of the gap compromised with modern science in their beliefs and teachings. They used the gap to explain the geological ages, the fossil record and the existence of dinosaur skeletons. Obviously, this was wrong.
There is no reason to bow to modern science in any of these areas. Creation with apparent age (meaning things looked mature at the time of creation just as Adam was created as a mature adult and not as a baby) and Noah’s flood could easily explain the geological structures as we have them. However, a weak argument in favor of a position is no reason to reject it. The gap I am talking about is not a scientific accommodation but a biblical doctrine.
