A statue isn't enough evidence of mistranslated Sumerian texts proving a group of gods came to earth and started the human species. lol. BTW, where was that statue discovered, and who is it of? I'm pretty curious; because it sure does look weird.

How is the ancient Egyptian religion supporting such an assertion? And how does it focus on Orion? To my knowledge, the pyramids of Giza weren't a universal cult object for all of Egypt (since the religion itself was made up of city-cults).

Anubis is a psychopomp, indeed, but the realm of Osiris is the Land of Reeds/Duat - the Underworld. The only astronomical association I can think of Osiris having is the Dog Star being used to calculate the annual calendar to find out when his, and his siblings birthday will be that year; due to the myth of Nut giving birth to all of her children on a single day, with the help of Thoth who won an extra day from the moon as a loophole after Shu forbid the year to allow her to give birth.
