PS: Aquinas' doesn't 'claim' that God is the unmoved mover, he argues to that conclusion. Not to say that he is necessarily correct, but it's not a claim.
PPS: I'm using terms from Aquinas' metaphysics, so the sense is not the same as we might take them. Eg 'motion' is our 'change'

That's not anything like an accurate summary of Aquinas' second way. Try again. Secondly, the argument doesn't claim that 'everything except for God needs a cause'.

You're saying that 'things which depend on something else for their existence' (i.e. contingent things) don't need a cause? That's a self-contradiction, and so can't be a sustainable objection to an argument.

Briefly, because the buck has to stop somewhere. The argument here is concerned with explaining why we see any causal regularities at all. What sustains existence here and now?
