Yes, I think you are right to challenge infinite chains.

In Aristotelian thought power is derived in two ways. Causes in sequential time which some argue can go on infinitely (not so satisfying theory IMHO) and hierarchically i.e. at anyone time where something is dependent at that time which is dependent on something else.

Because we are talking in the second case about what can be observed we can follow the chain down to dependence on quarks and energy. Which because they are changeable (have potential) we have to ask what there power is derived from.

This chain has to be of derived power (that is observed) but you cannot have derived power without actual power...something in the hierarchy must be sustaining the universe...or something like that.

In other words a hierarchical chain is logically not infinite since it must have two ends. If someone proposes there is something higher than us rather than that which is actually propping us up....... that is virtually a religious proposition.

The actual power propping us up from the bottom has the attributes of the classic western definition of God.
