Adama was a hybrid of ape and Anunnaki, Enki ... DNA manipulation according to the Sumerian Tablets, I understand.
And Lucifer was a negative spirit, just like a negative ion, anion, which means Adama could be declined to negativity in the 3D realm of duality on this planet, while Enki was an extraterrestrial being of higher dimension, Nibiru.
This is what I understand via deciphering the tablets!
