I believe in the Nephilim, because the Bible mentions them. But I haven't much of a clue as to what they were. I don't think I'm going to go buy the latest book on the Nephilim that's based on "the book of Enoch" which has been rejected as not inspired.
The Nephilim might have been Neanderthals.
I won't ping the list for this. That's firm.
I suppose you believe in a flat-earth as well since the Bible mentions that too:
"I saw a tree of great height at the center of the world. It was large and strong, with its top touching the heavens, and it could be seen from the ends of the earth." Daniel 4:7-8
"The devil took him (Jesus) to a very high mountain and displayed before him all the kingdoms of the world in their magnificence...." Matthew 4:8
Neither of these passages could be true if the earth were a globe.
