Observing early hominids from the outside, aliens might have said that the humans are “acting as though they want to maximize their inclusive genetic fitness”
I’m skeptical that this is true for aliens that are paying close attention.
Many ancient cultures had (attempts at) contraception. Claude tells me that Kahun Papyrus (~1850 BCE), the oldest surviving medical text, contains contraceptive recipes.
I bet that humans have been trying to have sex without getting pregnant as early as they realized the connection between the two, and first noticed that there were things to try. I would not be surprised if the aliens sometimes observed infanticide.
