I’m confused. How does the Big Bang suggest a universe coming into existence out of nothing?
Because Big Bang proponents have not a clue about the pre-conditions for the Big Bang?
You were affirming what @InCognitus was saying: "What the James Webb telescope shows, according to a NASA source, is that the universe doesn't originate from a single point: "The Big Bang happened everywhere at once and was a process happening in time, not a point in time. In other words, there is NO definite location within the expanding universe where the point of singularity can be found (I can agree with that). However Big Bang proponents had been using the "Red Shift" phenomena as evidence for, well, the Big Bang! Please review my post above for alternative cosmologies ably presented by Eric Lerner. He shows how Big Bang proponents are madly scrambling to account for ever more contradictions as more observations are being made.
I said "How so compelling!" to express my sarcasm. The Big Bang can only produce a finite universe (with finite number of intelligences) and definite starting point for time but an uncertain ending point (a possibility for finite time?). The point of singularity is finite. The resulting Big Bang cannot be infinite.
On the other hand, we have the Gospel as restored by Joseph Smith. It definitely teaches of endless generations of the Gods and the work will NEVER end. Therefore the universe has to be infinite and the number of intelligences has to be infinite. It is even taught that ALL intelligences (you, me and future spirit children) are co-eternal with God). It is the purpose of God to invite intelligences to participate in the Plan of Happiness and thus enable ever greater dominions and endless generations forever and ever (no end to infinity).
