If space, time, and matter began to exist, then the cause of those three things obviously can't depend on those three things. (That would require self-causation.) So the cause is spaceless, timeless, and immaterial. This is relevant because it sounds very suspiciously like God; and functions as a powerfully fulfilled theistic prediction that atheists never imagined and entirely failed to make.
Whatever caused the Universe to exist (i.e. space, time, matter), must have at least both the ability and disposition to cause those specific three things to exist. This is relevant because such a cause sounds very suspiciously like God; and functions as a powerfully fulfilled theistic prediction that atheists never imagined and entirely failed to make.
Even if God existed, creating a universe is not the kind of thing God would do. This is relevant because in the absence of seeing a reason to create something as highly specific as a universe, the likelihood that an all-good God would choose to create it is very low.
But no, plausibly God sees a “choice arena” for embodied agents as very good.
Physical reality (all of space, time, and matter) was never caused to exist](/universe/begin).

It matters that the Universe began to exist because otherwise it becomes incoherent to say it has a cause.
By way of response, however:
Theism is false. There is no God to create the universe.
True explanations do not feature “God”.
This page analyzes eight arguments:
This is relevant because if we cannot rationally invoke God's activity as an explanation, then God is probably not the cause of physical reality.
