ELI5: Is it possible that our solar system/galaxy is an atom/molecule for a larger organism?

The more important question is what reason do we have to believe it to be true? In science, we assume things to be false (referred to as the null hypothesis) until there is evidence to show otherwise. Sure, it is *possible* that the solar system exists within another system we can't detect but the far more parsimonious solution is that it doesn't. It is possible that an invisible pink unicorn is sitting in the chair next to me right now but it's much more likely that there isn't one.
