The answer, technically and scientifically, as far as I have determined is that we don't know. More precisely we cannot know.

The one agreed upon fact about what went Big Bang is that, since it is the one point of origin of out whole universe, we cannot know what came before it we have no information about its nature before it banged. To know this we would have to have detecting instruments in some meta-universe, observing this one sending us signals from before time as we know it existing.

Can that happen?

Maybe. It is possible, I guess.

Is it probable?

Nope.
