I like the suits, I'm not worried I'm still very convinced they're punking us by giving this away and that there's another race besides the tall humanoids. One that's a creature underneath, but uses the suits of their masters and ends up helping humanity, again. Yes it's true many religions/cultures portrayed their gods as very human-like; especially the pantheistic gods who have individual personalities and character faults. Zeus was always cheating on Rhea etc., but a common theme is that there are always classes of less tangible creatures mixed in with those "'gods". In the Greek myth, at first the Titans were actually the Elder Gods in the cosmology. Basically the first ruling class of true Gods that later gets replaced by the gods of Mt. Olympus. This puts the Olympian gods in the position to punish, and make war with the Titans. In many cultures there is the image of the old, bearded god figure like Odin, the Judeo-christian god image, Zeus, and to an extent Osiris. Although people in the past assigned human characteristic to a lot of the ruling gods, there's mention of other forces in a lot of the earlier thoughts of those cultures. The Titans/Elder gods are just one example, and later on in the myths they are more anthropomorphic, but I don't think these are the tall human "gods" spoke of in alien astronaut theory.
Even in the Judeo-christian myths you have characters like Jehova, who sounds like he actually could have been wearing some giant suit, or a weird creature himself. The many different choirs of angels are interesting, and the archangel Michael is said to be extremely tall when he manifests.
If you take it to alien astronaut theory and try to connect to the myths, there's still mention of non-humanoids when you really look at it. Daniken doesn't focus on this like some others do, because even for serious researchers there wouldn't be much to go on. Daniken does sometimes cover these things. The mysterious "Watchers"/Anasazi/Ant-people or what looks and sounds like our current idea of the grey aliens are possible contenders with the saucer craft being included.
Then you have things that are more Lovecraftian and in the vein of "at the mountains of madness" coming from some of the Egyptian/Sumerian stuff mixed in with the more humanoid sounding gods.
Still so many possibilities if they really dive into either the mythology or alien astronaut theory. People who theorize that the grey aliens were the "Watchers" (or some variation when translated from other cultures) think they may have been a slave race of the interstellar humanoids at some point in the past.
I'm not saying it has to look like E.T. But they could easily place any creature design in that subordinate role, aka what became of the Titans, the classes of angels, various creatures of Norse mythology, and what some think happened to the alien greys by the Nephillim/Annunaki of AA theory.
Not saying I believe all this stuff, all the analogies found cross-culturally show is that these myths of very similar characters took shape in different cultures and language, most likely being transferred from culture to culture. When you trace it all back, it leads to Egypt, the middle-east/Sumer, and ancient India. Where we first see things like the flood tale. When monotheism took over much of the other characters of the myths were forgotten or relegated to being in one of the choirs of angels. Even the pitchfork, and three-pronged staff of the Devil and Lucifer could relate to Poseidon/Triton and Hades. The caduceus appears a lot too.
