Why all god claims fail.

[Neo-Scholastic]

As soon as you postulate a super hero as the cause of that cycle, then it begs the question as to what caused that super hero, and what caused that super hero and so on. The problem is called "infinite regress".

So what then is your solution to the infinite regress?

This problem of infinite applies only to any sequence in which potential posterior causes necessarily depend on actual prior causes. The dependency of the posterior on the prior is what distinguishes an accidentally order sequence from an essentially ordered one. The solution to an infinite regress in an essentially ordered sequence is having a fully actualized initial member to the series, a first cause, that is not contingent upon any other. In your words, that would be a "super hero" the greater than which cannot be conceived.

However, if you believe all causal chains are accidental sequences, then of course, a world of non-contingent causes could extend into the infinite past without contradiction. This position comes at great cost. Such a world would be absurd since there would be no reason for posterior causes to follow prior causes. You can assert that they do as a "brute fact" but that is the opposite of supplying a reason. It's a simple choice based on blind faith about in what type of world you believe we live.
