I believe that:

nam-lu-ulu is the neanderboons
lu is a neanderboon
dingir / ilu is Celtic Royalty
ziusudra is a Celtic King

Ziusudra is also known as Utnapishtim and Noah.

They flooded Dilmun aka Bahrain because the nam-lu-ulu were too much trouble.

They'd already modified the neanderthal with baboon DNA to nerf the neanderthal.

Female Horites aka nam-lu-ulu survived.
