Well I am new at this... the texts are images, so yeah, they are, most likely open with interpretation, both in written languages post dating the hyroglyphs, ect...
Aeon... Eons... eternally... and Gods, well they might as well be surface dwellers immortalized in the skies.
Why make the extra effort of symbolizing a rising sun with anything other than a God.
That's the plain difference, one is night, the other is day, and the third is a time God, an event.
So I reread your thing. Horus is an event, and the others are events as well. So... Aeon the Aeon which is mix of Ra and Horus is most likely a birth of a new God.
So... how many Greek and Roman gods gave birth, so, maybe they are events in the skies.
Is that what you are asking?
From memory, Ra and Horus are strikingly similar, so Horus is probably born of a realization as you mention, and Ra is the Eternal God.
I'll guess, Ra is the Day, and Horus is Born in the Day. Horus is a hawk right? So maybe 10,000+ years ago, there was a mortal who ritually symbolized a hawk and wished to be immortalized in nature.
Native Americans might have something in common, they use parts of hawks in their rituals.
Jesus, do Pagans stand in the center of a pentagram with medicine bags, like Native Americans stand in the center of a medicine wheel?
I am asking because I don't know...
You guys watched this already, right?
