Just another one of those things that makes you go “huh!...what da hell?”
Niburu is said to have a planetary year which is about 6000
earth years long. There is a lot of mythology about it. The Annunaki are supposed to come from there.Those that stayed behind the last time Niburu enetered the inside of our solar system supposedly became the gods of ancient Egypt.Noah was said to have known them.
Star Gate TV series and the Star Gate movies were born from that myth.
Google “Annunaki”. Makes for interestig reading.
Zecharia Sitchin collected a lot of the Annunaki myths and
embellished them with geomorphological insights.
Sitchin died last year, after inaugurating a genome project
which will trace the genes of the Annu in human beings eventually, from the bones ( DNA) of an allegedly known son of the Annu.
Sitchin had been predicting this astronomical find for over 40 years.WEIRD! His books are published in many languages, including Chinese.
