Clearly not firm enough to support YOUR belief. As I said, Our Mileage May Vary.
When you get right down to it, there is very little that any of us know First Hand, directly using our own senses and having our own experiences. What we claim to "know" is really highly plausible second hand evidence, essentially hearsay which is not blatantly contradicted by our own personal experiences.
Did you know that as late as 1915 there were reputable physicists who were not convinced that the atomic theory was true? Ernst Mach (he of the Mach supersonic speed scale) was one such. Till his dying day he did not fully accept the atomic theory as more than a convenient rule or heuristic for tying up the measurements. This skepticism was finally worn away by the pioneering work of Albert Einstein (yes, that Einstein!) in molecular dynamics. Einstein's most quoted paper is on Brownian Motion in which he demonstrated very convincingly the molecular and atomic theory of matter (he published this in the pre-quantum physics days before quantum theory hit the big time in 1913). Nowadays, no one doubts for an instance that atoms exists, even though no one has every seen an atom (they are too small to be resolved by the human eye or any optical microscope).
So have a caution and distinguish what you know for damned sure and what you hold provisionally and what might be true, but not well supported by empirical evidence.

I have been aware of the Einstein thing and am fully in agreement with you on having doubts about everything, including visiting aliens. Atoms, which can be seen as either waves or particles are useful concepts and may one day again bow out of existence when more is learned about the fundamentals of the universe. So it goes.
