makes sense
Joy-riding aliens discover Earth 100K years ago, teeming with life, and find the hairy pre-humans romantically irresistible.
Soon enough, little intelligent hybrids are popping out all over (this explains why intelligence and civilization seemed to arise almost simultaneously around the world).
The aliens, like sailors on shore leave, evntually depart and leave behind their love spawn, of which we are the current version.
Today’s alien visitors are descendants of the originals, raised on sagas and tales of the most desirable creatures in the universe, the hirsute hominids of Earth. Reliving the adventures of their forefathers, they travel to Earth of today, but are sorely disappointed. Repulsed by our hairlessness, they occasionally abduct humans in an attempt to figure out what went wrong.
They feel some responsibility and sympathy for their progeny, which is why the aliens haven’t shut down their failed experiment yet.
Nah. Today’s aliens run for office and become president, attorney general, secretary of DHS and about 2/3 of congress.
