Nondualism vs Dualism

[Lemon Curry]

I believe that in our pre-existence (pre-bigbang) we existed as 1 solid entity built upon two perfectly symbiotic states of matter. I believe this entity held consciousness and consciously killed itself in order for more creation to spring forth. I also believe that we have the history of our making from the big bang until present written in our DNA.

Even if you think I'm full of shit, I'm curious what y'all believe concerning dualism vs nondualism. I say both

Big bang, AFAIK, covers the expansion of the Universe from a singularity through to its large-scale evolution.

Strictly speaking, time only began at the formation of the singularity.  Therefore, to use the term 'pre-big bang' is invalid and has no meaning.

In addition, before time began, space did not exist.  Therefore, the pre-big bang matter of which you speak cannot have existed because the space required to contain the matter didn't exist. 

Penrose, relatively recently, argued that time, pre-big bang, did indeed exist since the mathematics allows for this.  However, he also argues that time differences, pre-big bang, didn't exist.  Just when I had all my ducks in a line too.

Man, that was some trip you went on.
