BUT, it is true that every element within every molecule of your body did come from stars, and that all the elements heavier than hydrogen were created within either a star, or in a supernova.
So it is absolutely true that you are stardust, just not in the way you asked.
We’re mostly stardust, but maybe not all stardust. Hydrogen makes up about 9.5 percent of our bodies by mass and all the hydrogen in the universe was created in the big bang. While it is likely that the hydrogen in your body was part of a star at some point in the last 13 or 14 billion years, it is not an absolute certainty.
Are you referring to us being about 70% water? Water is 2 hydrogen atoms and one oxygen atom. Hydrogen is a very light element compared to oxygen, so hydrogen makes up 9.5 percent of our mass while oxygen makes up about 65%. Bear in mind that both oxygen and hydrogen exist in other molecules besides water in out bodies as well.
Spirit? No.

Wouldnt it be 79.5%? Or is that subsumed by the standard 70%
