In the previous question about the Golden Calf I thought it was suspicious that neither Moses left the "chain of command" just in case, neither Aharon offered himself as Moses' replacement.
Also, when the people demanded to replace Moses with an idol, nobody wondered how can Moses be replaced with an idol (related "the-realistic-expectations-from-the-golden-calf").
I do not accept the simplistic idea that they were all fouls and idolaters and all they wanted was idolatry.
Why did they think that Moses as the leader of the Jewish people can only be replaced with an idol: was Moses clearly non-human (his face radiated?) or only a non-human could lead the people or only a non-human can mediate between them and G-d?
