The satan (hasatan) was never kicked out of heaven. That's not in the torah or the bible. There is no devil in the old testament(torah). The god in the old testament has no rival in power, which is why there is no devil. Hasatan is not a devil or a demon, he is god's(yhwh, el, el shadai, el yon, adonai, hashem) prosecuting attorney. He points out fucked up stuff mankind does, or might do(see book of Iyov(Job)).
The satan doesn't become the devil until the book of jubilees, which is neither in the torah nor the bible, as "mastema".

I was watching a Yale lecture on the hebrew bible and one theory the professor pointed out is that the temptation and "fall" in the garden of eden could actually be a metaphor for sex. The serpent(phallic symbol) tempted the woman to eat fruit(sexual metaphor) then gave it to the man to eat(sexual metaphor).
