Yeah that pretty much lines up with what I've read.
From the sources I trust most though, it seems like Marduk was another planet that was destroyed.
There was also a Martian civilization that was destroyed as well. For proof of that look up the face on mars and the CIA Mars gateway interview.
I read the remnants of the martian civilization was cloned and transferred to earth by Yahweh. You can read more here https://www.lawofone.info/results.php?q=yahweh
It seems lime there were also native Earth inhabitants who evolved from apes, and at least one other race from that Law of One material I linked to above. Out of everything spiritual I've read I've heard from good sources that it is very accurate, and it has resonated with me the most, so I highly recommend it.
