?? I'm not confident in asking anything or pretend to know things I don't. I'm just coming from a layman perspective, and pondering really a simple question. Science is always about verifiability and causality right? Then where do all matters come from if it cannot create itself?That's too technical a discussion for me to bother. You simply don't have enough of an understanding of the current state of the art in cosmology. So I don't understand why you feel so confident asking that question. It's not like you studied the various ideas on the origin of reality, and came to the conclusion that some things are unexplainable.
