There is just 4 possibilities:
 * The aliens and humans share the same ancestry somehow, but this is unlikely
 * life evolved in a very similar way on other planet/s than Earth and the 'Otsutsuki' (that's not even their race name, just one clan, there might be more) have the same amount of chromosomes as humans do, allowing for breeding, which might be the case
 * humans are in fact creations of the aliens, wouldn't surprise me, got my own theories about that
 * creation deity which made both, i don't think so
