I think we'll never know because the way our brains are wired. If you ask yourself "what's the origin of reality", there are 2 kinds of answer:

1. Our reality has been created by someone or something. This could be God, or some civilization that lives in an upper reality (so we are being simulated), it could be randomness, anything. The point here is: something started the fire.

2. It has always existed. No beginning, no end.

Now, answer 2 is something we (humans) can't grasp; our brains can't think of something that has existed forever. Imagine no beginning at all... that's hard to grasp (if not impossible), I think.

Answer 1 is just a "local" answer. The immediate follow-up question would be: "so who created our creators?". And again, the same two answers apply. At the end of the day, answer 2 seems the only answer I can imagine (because answer 1 just starts a loop of questions/answers that is never stopped).

Edit: I'm not talking here about the origin of our universe. That can be discovered just fine. I'm talking about reality as in: the reality of everything.
