Now here's an interesting thought: Would you have deduced that stars are distant suns if you'd lived in the ancient world?
Apparently the only pre-modern people (i.e. pre-Giordano Bruno) recorded as making the claim were Anaxagoras and Aristarchus of Samos [0], but their ideas were completely rejected by contemporaries.
In retrospect, it just seems so blindingly obvious that I'm tempted to believe that I too would have seen through the Aristotelean BS.
But surely there must be aspects of reality that will seem similarly obvious to future generations, and yet I don't feel any insights coming on.
I should say, Aristarchus is the ideal of maximizing information from minimal data:
>Aristarchus of Samos (Samos is a Greek island in the Aegean Sea) lived from about 310 to 230 BC, about 2250 years ago. He measured the size and distance of the Sun and, though his observations were inaccurate, found that the Sun is much larger than the Earth. Aristarchus then suggested that the small Earth orbits around the big Sun rather than the other way around, and he also suspected that stars were nothing but distant suns, but his ideas were rejected and later forgotten, and he, too, was threatened for suggesting such things

It's incredible what knowledge we'd have, if it weren't for Christianity and the Dark Ages it engendered. There are tons of palimpsests like this, like the Archimedes Palimpsest, in which the beginnings of calculus was invented, almost two millenia before Newton, but were scraped off to make yet another Bible. Imagine what the West could have accomplished if monks weren't so busy erasing science and math.
