This has always been my interpretation. God made Adam and Eve first, but they weren’t the only ones who lived on Earth. 

Others would not be important, as they are not a direct lineage to Jesus Christ.

Y'all miss the big story in the bible. God didnt create homnids, there were dozens of neanderthal/habilis/erectus type hominids pre bible. The garden of eden was a zoo, and adam and eve were genetic experiments. God is just a geneticist who overclocked some apes and sent them back to mix with the rabble. Then once his genetic experiments got established in the ecosystem, wiped out the majority, except the ones with the most successful mutations (noah and his family) and wiped out the rest of the homnids (the flood), leaving only his selected genetic group to repopulate the planet.

Thats how I always see it. God, not being born on Earth, is by definition, a technologically advanced alien being.
