You're whole 'act' goes directly against the written Scriptures.
The Genesis 6 and Jude 6-7 Scriptures is very easy to understand that a specific group of angels left the heavenly and came to earth, and mated with the flesh daughters of Adam, and the result was a hybrid giant offspring called the Nephilim in the Hebrew. Their great stature and hybrid nature is even described in several later Bible Scriptures.
Believe God's Word as written, or don't, I don't care. But you won't change this as written, nor will you change history about it either.
Testimony by William F. Cody (a.k.a. Buffalo Bill) in his autobiography said the following:
"While we were in the sandhills,, scouting the Niobrara country, the Pawnee Indians brought into camp some very large bones, one of which the surgeon of the expedition pronounced to be the thigh bone of a human being. The Indians said the bones were those of a race of people who long ago had lived in that country. They said these people were three times the size of a man of the present day, that they were so swift and strong that they could run by the side of a buffalo, and, taking the animal in one arm, could tear off a leg and eat it as they ran.
These giants, said the Indians, denied the existence of a Great Spirit. When they heard the thunder or saw the lightning, they laughed and declared that they were greater than either. This so displeased the Great Spirit that he caused a deluge. The water rose higher and higher till it drove these proud giants from the low grounds to the hills and thence to the mountains. At last even the mountaintops were submerged and the mammoth of men were drowned."
