They make my entire life, as an Earthling, completely worth living.

I have already tried to explain to few people that every single atom in their bodies or in the entire solar system for that matter, comes from star birth clouds like those ones, and ... well... people would prefer watching stupid TV shows rather than learning just a bit about their own history, and quite a fascinating one in fact.
