I especially call bullshit at when those morons say that angel drawings represented flying aliens. That "ancient men where not stupid, they drawed what they saw, but couldnt explain". Seriuslly, if man drawed what he saw, than why hasnt any of these scrolls or drawings shown a flying saucer or something. Ancient age people must have been pretty fucking stupid and blind if they saw a flying saucer, a completely white, naked and hairless tall motherfuckers with gigantic heads and to show others what they saw they fucking drawed bearded dudes with birdwings and white tunics. Seems pretty legit to me!
Actually ancient people never depicted angels as shapely men (and nowadays mostly women) with wings.
One form of angel is described as wheel with hundrets of eyes descending from the heaven in flames. Humanoid (but if that means "looks like a human" or "it has hands and a head", we don't know) angels used them as transport.
http://en.wikipedia.org/wiki/OphanimThen there's a lot of really odd ones, the only common theme seems to be that they have wing like appendages, which they use to cover themselves. Because they wanted to bring messages, but apparently everyone that saw their real form was driven mad.
The stories changed a lot over time, and apparently people don't remember the uncomfortable stuff. So we kind of remembered humanoid and wings, and that was kind of pretty so it's what's left.
