Observation: the Universe is spreading more or less homogeneously (That means at the same speed in every direction).
Since it is spreading, then, if we turn the clock backwards, it will come together.... closer and closer until it is at one single point in the space-time continuum.
What happens after that one point? we don't know. No one knows. We may speculate, the human mind is great at speculating...
.One option is an entity from some different dimensionality, that simply created a 3+1D drawing.
.Another option is that the space-time continuum is infinite and present zero average energy, but some quantum fluctuations bring forth a few virtual particles here and there and, on occasion, these come together and generate real particles. For each particle, a suitable anti-particle is generated also, so the net energy content is ZERO. The infinity of space-time makes it possible that a location exists where too many of these real particles are generated, thus yielding a Universe.
.Another option is.... lots of Universes.
.Another option is... we're inside the matrix.

Any guess is as good as any other, as long as we're aware that they're only guesses.
The trouble starts when some people claim they have the answer, but have nothing to support it, and push that answer onto other people as if it was the magic bullet. And harm those people who do not accept that answer.
