All ancient names for the same. First written about by the Sumerians who believed them as their creators. They lived much longer than we do now. :)
Zecharia Sitchin got his 15 minutes of fame coming up with fake translations from the Sumerians about Anunnaki from the planet Nibiru. Then that vile hoaxter Nancy Lieder took it further and claimed the world would end in 2003 as Nibiru shot through the solar system flipping planets on their poles. When that didn’t happen, she changed it to 2012. The UFO research business is full of crackpots, and as a result you can’t believe any of them.
