How can we be sure this is reality?

Your reading comprehension needs work.

What did I miss? You mean axiom?

No, I mean this:

So saying science is an unprovable assumption is absurd.

I didn't suggest any such thing.

Sorry, there is a huge difference between the starting points scientific method uses and the "axioms" laypersons use as definitions.

I'm not going to fall for or allow a si fi woo Matrix garbage be equated to lagit science. QM is lagit science. The Matrix is si fi woo.

It is the same crap that allows the word "create" that a scientist may use when describing an observation, and the theist who twists that word to mean a magic cognition as a cause.

It is true when a scientists starts something they are starting somewhere, but they are not starting with nothing. They are still using data, and observation and testing. That is still not the same as pulling something out of your ass.

I didn't suggest any of the above, either. You read far too much between the lines.
