Yeah. I’ve never understood how the West can proclaim Herodotus the “Father of History” and then proceed to ignore everything he wrote about Egypt.
Except that they’re not anywhere near the same. First of all, in Egyptian mythology, gods are not immortal, just very powerful, and able to return from death; hence the story of Set chopping up Osiris. Greek mythology, however, posits the gods as immortal, although still damageable, albeit only by titans or other gods; hence all of Kronos’ children still being alive after he ate them.
Also, Amun-Ra is often thought of as a singular being with two aspects, while Zeus and Helios are never thought of as singular. Note also that the Greek and Egyptian creation myths are also entirely different.
They even list Heracles as a god in this despite the fact that Heracles was merely a demigod in Greek myth; the guy palled around with the Argonauts (the original Justice League/Avengers) and had his Labors.
It’s very interesting also that they claim Set as the equivalent of Ares when Set is a trickster god and Ares gets outwitted by pretty much anyone with two brain cells to rub together.
tl;dr - different cultures produce different mythologies, and trying to make two pantheons (aside from Greek/Roman) line up is fairly impossible to do with total accuracy.
