Not only that, Jesus Christ tells us that in the beginning He made us male and female. That would be kinda hard to do if in the beginning we were nothing more than pond scum :o)
That he doesn’t tell us HOW we came from pond scrum does suggest that that information is not of cardinal importance. Human nature is pretty much a given. Even if we are in the lineage of pond scum, we ought not behave as if we were.
