Yeah, I threw that post in there because this thread has almost ran it's course and not too many besides you would see it.
But it's biblical:
Gen 6:2 That the sons of God saw the daughters of men that they [were] fair; and they took them wives of all which they chose.
Gen 6:4 There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare [children] to them, the same [became] mighty men which [were] of old, men of renown.
Deu 3:11 For only Og king of Bashan remained of the remnant of giants; behold, his bedstead [was] a bedstead of iron; [is] it not in Rabbath of the children of Ammon? nine cubits [was] the length thereof, and four cubits the breadth of it, after the cubit of a man.
Og's bed was ~18 feet long.
There's enough masonry in the Pyramid to build a highway from New York to L.A. Also the Egyptians plastered everything they built with hyroglyphics, the Great Pyramid has none. Also there is no record of the construction of the Great Pyramid, something of that magnitude should have been recorded. The builders, if human, had help, at least.
There will be a third influx:
Luk 17:26 And as it was in the days of Noe, so shall it be also in the days of the Son of man.
Luk 17:27 They did eat, they drank, they married wives, they were given in marriage, until the day that Noe entered into the ark, and the flood came, and destroyed them all.
The days of Noe means the days of the Nefilim's offspring. The Nefilim's offspring were killed in Noah's flood.
