'Uncaused Cause' or 'Unmoved Mover' arguments are very easily refuted. They rest on the intuition that uncaused events are impossible, and thus require.. An uncaused Being to fix..? That's what we call an 'ad hoc' solution.

What is highly unlikely is that humans can trust their intuition when it comes to matters like the creation of the universe, the beginning of time, and other such notions. Nothing in our experience has prepared our species to consider such matters. Arguments that rest on everyday intuitions regarding concepts like 'infinity' really should be rationally scrutinized and not simply relied on because they are 'intuitive'.
