"You have the Adamic race and you have the pre-Adamites. That means there were people on the earth before Adam"

"My present view is that “the sons of God” are the idolatrous pre-Adamites. This means that this phrase is best translated “the sons of the gods.”"

"The Custodians explained that much of their oral and other traditions had been lost including the timing that the royal class was to be awakened. They said the royals were not supposed to be awakened until after the next solar event."

"who are the “sons of God”? Are they human or some kind of angelic beings? If the sons of God are angelic, then is the angelic/human cross what accounts for the greatness of the Nephilim?
Regardless of the answers to these questions, we would assume that all of the Nephilim alive at the time of Noah perished in the flood. However, Genesis 6:4 also seems to indicate that the Nephilim reappeared after the flood: they were “on the earth in those days—and also afterward”—that is, after the flood.

"Several of the Inner Earth inhabitants, huge giants, detected our boat on the river, and were quite amazed. They were, however, quite friendly. We were invited to dine with them in their homes, and so my companion and I separated, he going with one giant to that giant's home and I going with another giant to his home.
"My gigantic friend brought me home to his family and I was completely dismayed to see the huge size of all the objects in his home. The dinner table was colossal. A plate was put before me and filled with a portion of food so big it would have fed me abundantly an entire week. The Giant offered me a cluster of grapes and each grape was as big as one of our peaches. I tasted one and found it far sweeter than any I had ever tasted outside. In the interior of the Earth all the fruits and vegetables taste far better and more flavorsome than those we have on the outer surface of the Earth.
"We stayed with the Giants for one year, enjoying their companionship as much as they enjoyed knowing us. We observed many strange and unusual things during our visit with these remarkable people, and were continually amazed at their scientific progress and inventions. All of this time they were never unfriendly to us, and we were allowed to return to our own home in the same manner in which we came… in fact, they courteously offered their protection if we should need it for the return voyage."
Another different account about a visit to the hollow Earth was cited by another Norwegian by the name of Olaf Jansen, and was recorded in a book called "The Smoky God", written by Willis George Emerson."
