You are a descendant of supernovae!

"Every atom in your body came from a star that exploded.It really is the most poetic thing I know about physics: You are all stardust."

You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution and for life - weren’t created at the beginning of time.
They were created in the nuclear furnaces of stars, and the only way for them to get into your body is if those stars were kind enough to explode.” - ― Lawrence M. Krauss
