Young Earth. Though am open to the day-age view.
6-12 thousand years at the most.
... What? There are enormous, even vast amounts of scientific proof to completely discredit any notion of a young earth. Have you never taken a course in Anthropology or Biology?
The funny part is that he is evidently married to a geologist.
But true. She is old 🌏. Astronomy tends to favor young earth however.
Huh? Even young-Earth creationist astronomers like Jason Lisle acknowledge that the distant starlight problem poses a significant difficulty for a young universe model.
Anyway, for me, I'm definitely a fan of the gap theory (often called the gap principle) - as there is too much scientific evidence contradicting a young Earth, and the exegesis makes sense with it.
Is that the one where God creates, destroys, and re-creates everything, and fossils are from the first creation?
Yes, I think that the "Earth was without form and void" refers to the time on the Earth over geological eons. During this time at some point also occurred the rebellion of 1/3 of the angels led by Satan. Then God remade the Earth "anew" (and I believe that creation referred to a mass extinction event, though I can't be totally sure) and life was breathed into Adam. I believe that humans were created in the special image of God, but this was done in the body of an evolved ape-like ancestor, based on DNA similarity. The exact cosmological details are known by God, but I generally accept the scientific consensus with regard to these questions, with the exception of the fact that I hold to a rather strict view of monogenism.
