I thought we established these Pyramids survived the flood of Noah and the Egyptians just inherited them and built their own around them. Whatever tech within has been obliterated by time.

The people before the flood lived up to 1000 years and they could do anything as a being who "looks" and is "like" God. No physical aliens or demonic entities involved. The fallen angels literally fucking humanity to create hybrids theory is bat shit. The Bible/Torah translation means men of tyrannical intent such as dictators of the line of Cain fucking with the good people(Seth's line) who gave in. That's when the unity of good and evil occured. Hard to believe that's what it's saying since these tyrants are a norm today, they can enslave millions(North Korea, China) and have caused mass murder(Hitler, Stalin, Polpot), but the Torah is showing you their origins. Men calling themselves after the name of Elohim/God, for ex. LORD Tom and he has authority to rule over peoples like YHWH.

I imagine they almost left to space, but then the flood wiped them out, or they were just having orgies everyday and the gays ruled in those last days. Yeshuah Jesus said our end will be like the days of Noah too, eating, drinking, marrying and shocked when the floods came to wipe them out.
