Where did the universe come from? Atheistic origin science has no answer.

[FallentoReason]

To whom will He demonstrate this to? Why is there even a need to do this in the first place?

for spiritual beings: angels, human beings, God wished to show his attributes such as justice, forgiveness, mercy, and self-sacrifice for the benefit of another in a concrete form rather than in abstraction.

So we exist to be shown something?
This idea that we weren't asked to partake in "God's theatre" but are here anyways always makes me wonder where this so called 'justice' is. Think of those residing in Hell, who were forced to exist on earth, quite possibly never had the slightest clue of what the 'bigger picture' was, and are now suffering for eternity for it. And God calls this a Divine Plan?

another reason God created the universe - to provide human beings with the preparation and training for their position in the new creation. After the 1000 year reign of Christ on earth (old testament promise), this universe will be completely destroyed with fire and will be replaced with one that will be absent sin and evil; and the current physical laws like entropy, (2'nd law of thermodynamics). people will have enjoyable and fulfilling work (no fatigue or drudgery associated with it) in the new creation which won't be under the curse of sin.

This is just white noise to me...
