As far as we know.......and we probably will never really know. But yes, it seems that would be so. Our universe did have a beginning. But that should not be equated to matter/energy having a beginning.
Not really. Not necessarily.
Time and before/after simply doesn't apply to the universe before expansion.
There was a hot, dense point. (Time is irrelevant), then it inflated and then that inflated "lump" expanded and is continuing to expand.
