My understanding is that the Anunnaki are a male-oriented group that came originally from Orion but for some reason migrated (in whole or in part idk) to Nibiru. Nibiru and Earth both have central cores that come from the same collapsing star so they are linked. Nibiru has a 3600 year cycle around the sun and it comes close to us for a few hundred years every cycle and the Anunnaki come to Earth when they are close pretending to be gods and impregnating our women. This has been going on for something like 300,000 years.

The Anus (lol) are 4D beings and when they come into 3D they are metallic reptilians. When they mate with human women the genetics are off so childbirth is painful (bible stories are from them btw). The children born from these pairings are kings and queens and bloodline families. All major religion, media, secret societies, govt are created by Anu lies. They need Earth and Humans for work and energy, but for some reason their evolution is now tied to ours.
