Yes it's one of 3 creation theories I know. There must be more than these 3, but ... and please this is a deliberate simplification, so try not to over-react:Isn't it called creationist myth? My history knowledge doesn't extend that far so l stand corrected if wrong.
1) God i.e. the creator of all, created the world and man in, literally, 7 days,
2) Mankind evolved, un-interupted, despite the unresolved anomalies, which still perplex scholars.
3) Mankind is a hybrid species, created as a worker-race, according to accounts recorded on clay tablets, uncovered in the middle-east. This would essentially make our creators 'missing', and it would make us (human beings) the link between the primitive local species and our 'gods', as per the book of Genesis.
I'm not 100% convinced of any of these, but if I had to go with one, I'd say #3.
