Well, that's only because in reality... for there to be an effect, there is a cause.
Your statement
assumes causality. Perhaps the universe is not an
effect. Perhaps it merely is.
But even if we accept your premise, it still leads you right back to Alan's question. What created God?
There's no regression... reason does not require certainty to hypothesize.
That you say this shows that you lack both an education/knowledge regarding the First Cause issue, as well as any kind of understanding of it.
The infinite regression of causality is inherent to the nature of the First Cause question. The regression is, in fact, fundamental to arriving at the question of a First Cause to begin with. What caused today? Today was caused by yesterday. What caused yesterday? The day before that. What caused the day before yesterday? The day before
that. So on and so forth. It is through this regression that we arrive to the question of
what caused the universe? If you demand that there
must be a cause for the universe, then you why don't you demand that there also be a cause for God?
That some must have preceded God, does not undermine the potential for God to exist.
But First Cause arguments aren't about
potential for God's existence. A First Cause argument claims a
necessity for God's existence. Those are two drastically different things. There's
potential that life exists somewhere else in the universe, but it's not
necessary.
