I can say that the context of the discussion was an assertion that I made that the Egypt-Greece-Hebrew civilization is what collectively invented the idea of good and evil. He corrected me saying that it was a major feature of this collective civilization.
Just now I tried going through Wikipedia, and I'm fairly certain what he was referring to is generally called Neolithic civilization. It was much more sophisticated than is commonly understood.
Especially since Neolithic civilization spans ~6K years, and appears at very different times in different regions, with cultural artifacts appearing in different order.
As for "good and evil", evidence so far says it probably started with Zoroastrianism, which is really at the tail end of the neolithic. Your Quora user either has access to not commonly available research or is misremembering.
RE: good and evil, his specific point was that societies were organized around the broad principles of a grand fight of one set of deities imbued with good traits fighting against another set of deities working against the good ones. Zoroastrianism is notable not because it invented good and evil, but because it was the first stab towards monotheism.
