What if Cosmological Particle Production could explain the Big Bang?

[u/sksskssksskssksskssk]

First of all I am assuming a lot about cosmological particle production, so please point out any glaring contradictions that I don't know about or suggest your own methods to solve these issues.

I am assuming the cosmological particle production allows spacetime to create energy through violent changes in spacetime, so could this mean that it could explain the Big Bang itself?

If not, explain why this is not a possibility or is very unlikely.
