You're assuming any of this has an existence independent of your mind, that more than the present moment exists, and a whole lot of other things.

You make reasonable assumptions, but proving them is hard, because any attempt you make to prove them still end up being filtered through your potentially unreliable senses.

In practice we decide to just accept that a material world with semireliable senses exists, because the alternative is no certainty at all.

The alternative without falling into skepticism is idealism. But scientific explanations of many things like disease, chemistry and physical forces are very compelling compared to the world just appears the way it does as ideas in our mind.

In other words, proofs cannot exist without axioms.
