Sounds interesting. Hopefully I can find time to take a look this weekend. I've also wondered about possible advanced technology in the antediluvian world. Of course their advances may have gone in a completely different direction than our own.
I do like Russel Humphrey's work. His prediction of the magnetic field of Uranus was epic. He has an interesting theory on starlight, but although I liked it when I first heard it, I think Dr. Harnett's theory is more likely the right answer.
I'm always open to considering new ideas, but the Bible is always my firm foundation.
