As simple as possible to summarize the best way you can, first, please. Feel free to expand after, or just say whatever you want lol. Honest question.

    We have facts up to big bang. It (as usual with these things) gives us just more questions than actual answers to how the universe came to exist. I argue that it always did and always will.

    I think this is faulty logic. How the universe came to exist is fine, and we don’t know, but that the universe “always existed” is a bit odd. You can’t have anything before space-time exists. In a sense that means yes, it “always” existed, because that’s the start of time, but in another sense it did not exist too, just time didn’t exist, if that makes sense. It obviously doesn’t really make sense because we’re unable to hold that concept in our mind, but time did come into existence.

      Unless I have missed something huge, time didn’t ever not exist. If you refer to big bang, what evidence says time started then? Sounds really fascinating but I have never heard of it

        How do you have time without space-time? The big bang is actually not the exact start of the universe. It’s pretty close, but not quite. It is the expansion of the universe. Before that it’s in a very dense high energy state, but it does exist. It explains how it went from this state to the current state, but not how it came into existence at all.

        I don’t think it’s believed to have sat in this dense high energy state for infinite time before the big bang, so it must have come into existence, not just existed forever. If that’s the case that means space-time came into existence. You can’t have time without space-time, so there is no time before it exists. At some point space-time exists, and as such there is no before, since there is not time.

        It seems odd to consider. How do things happen without space-time? We can’t really think about this concept, because we’re space-time beings. It doesn’t even make sense to consider. However, having an intelligence start things doesn’t help. It only then begs the question where they came from. Surely the universe just starting is more likely than an intelligence appearing for some reason, then it deciding to start the universe. That’s a vastly more complex set of circumstances.
