Heraclitus also
promulgated the
myth that humans were once as powerful as
gods, possessing 4 arms, 4 legs, 4 ears, 4 eyes, 2 mouths...and the gods tore us all asunder, for self protection.
As each individual was strecthed out, the thin bits broke, like silly putty, and that's why we have nipples, and genitals, and faces.
That's also why we spend our lives looking for our other half, and why sex feels so good...when we find him/her.
