If Nibiru had intervened with Earth some time around 5000 bc?

5300 bc Fallen Angels come to earth teach Sumerians agriculture and impregnate women, giving birth to giant hybrids. (Bible says there were giants) These giants build the pyramids. 3600 years later they return, now 1700 bc,(bronze age) this is a period of great changes on earth. Civilizations fall, new emperors come to power, species become extinct, the giant men are wiped out (this is the biblical flood of Noah caused by Nibiru) Now instead of living 1000 years, man now live only 120, such as Moses. It all make sense, does it not?

No, not so much.
For starters, there is no “Nibiru”. There was no global flood, and there is no fossil evidence to indicate that humans or their progenitors were ever taller than we are right now.
