We
are able to observe quite a bit about the rest of the universe, including quite a large number of stars. Spectrography is a fairly well established observation technology, and is almost certainly reliable (if it isn't then then the universe is really weird (like Matrix-weird). The basic model of stellar nucleosynthesis pretty much can't be wrong; if it was discovered in a an earlier more arrogant time we would be calling it a Law of Nature.
