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.

It does not say anything about time starting, ending, or anything. It is just a set of rules that approximately reproduce results we observe. It is not the rules of the universe. The rules we use in physics actually do not have a direction for time. It works the same in both directions, though clearly time does have a direction. It does not make predictions on if time started or if it will end, only what is the case for what we can observe right here right now.
Um, yeah the interesting part is that while physics itself indicate time as a one dimensional infinite band, (with possibly branching multiverses but I digress) we as humans attribute a beginning and end, as all we know consists of such objects and entities. Our mind is terrible at grasping infinity, it has even broken many curious minds that try to understand it and are a bit too tenacious in their search. In any case that is my proposal here, that it is an unanswerable question how the universe started. 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.
