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.
By way of response, however...
• ...space and time expanded from a nothing-point singularity
• ...general relativity's Big Bang from nothing model is true
• ...past-eternal expansions require impossible speeds
• ...total entropic decay as not arrived yet • ...total generalized entropy has not maxed out yet
• ...logically, the past must be finite
Theism is false. There is no God to create the universe.
True explanations do not feature “God”.
• …“God did-it” is just an appeal to ignorance-gaps
• …“God did-it” is just an appeal to magic
• …explanations don't compound the mystery
• …explanations don't explain “too much”
• …meaningful claims are verifiable (by senses)
• …meaningful claims are falsifiable/testable
• …explanations cite effective mechanisms
• …explanations are unificationist
