Not if time is a non-linear field.

No it doesn't.

You see the problem of ultimate origins destroys that idea.

It comes from somewhere you say, but then that somewhere has to come from somewhere, and that somewhere has to come from somewhere, this problem goes on forever and that makes no sense. The problem is identical for science and for religion. What was before the before, what created the creator etc?

All that it existing actually implies, is that it exists, no more, no less.

There is an explanation, but it is that time is not linear. I have a feeling it is not worth sharing right now but I will share a little bit.  What we call the past is a relative position, not actually an event that happened and is over, just one that relative to our position is past from our perspective.

There is no eternal ongoing aspect, existence is an instant and a constant. There is no problem of origination because there is no beginning nor is there an end, at least not in any ultimate sense. The linear aspect of time is due to relativity and position, but there is still the singularity of time, we call it "now" and it is instant, not eternal.

This idea of "where did it come from?" is silly, so is "where will it go?"

It is but not was and not will be, was and will be are nothing but semantics without a defined context.

It is originating as it ends, right now.

It did not originate, it will not end.

It is really hard for animals like us to understand.
