That's so deep I'm gonna need to take the rest of the day off work.
Think my work will buy it?

Except for most of those Hydrogen atoms. Which is like 60% of the total number of atoms in your body. So the 'every single one' bit is almost, but not quite, entirely unlike reality.

Yeah, I'm pretty sure this was covered awhile ago.

Yeah, but can they explain what would happen if life as you know it stopped instantaneously and every molecule in your body exploded at the speed of light?

... total protonic reversal.... =(

This is actually one of the first real things I grasped about our relationship with the stars/universe many years ago in grade school science class.  I'm greatly comforted by it, knowing that even though I'll never be up there in the stars, I'm sort of already there.

Cool, we're the leftover butts from the ashtrays of space.

But in between, our atoms were also in dinosaurs' turds and vomit

had no idea stars were considered a life form. Thanks science!

Just remember that you're standing on a planet that's evolving and revolving at nine hundred miles an hour.
That's orbiting at nineteen miles a second, so it's reckoned  A sun that is the source of all our power

Always was curious about how God did it 6000 years ago. Got it. Very informative

That just seems like splitting hairs for the sake of sentimentality.
The molecules in my body weren't forged in a star, only their comprising elements.

But all that star did was re-arrange subatomic particles.
So where do we draw the line?

Is it so special to think that all our stuff was created in the big bang?

NASA astronomer Caring priest explains how every single atom in our bodies person came from a star just and loving god in the moment before its violent death he bestoweth his love upon us. And that's a pretty damned blessed beautiful thing: "We are dead stars made in his image, looking back up at the sky heaven"

The carbon in our bodies does not come from dying stars - sorry, Carl Sagan and whoever this AW is.  Stars have the luxury of inefficiency, and operate on a multi-stage fusion cycle in which carbon is a catalyst.  It is necessary, but the amount of carbon required is equal to the amount of carbon produced. Humans have to settle for the lowest-hanging fruit, which is the dirty Deuterium-Tritium fusion reaction.

Everything post-Fe26 and much before that, can safely be said to be the product of gravitational collapse promoting less-efficient exothermic fusion or even endothermic fusion.  But not carbon.

You're missing an important point.

The carbon in your body is there because a dying star blew up and sent it to a new region of the galaxy, regardless of exactly when the carbon was made in the star's lifetime. It was precisely the star's death that distributed the carbon and made you possible. Otherwise... the carbon stays inside the star.

So, yes... the carbon in your body comes from dying stars. No star death = no carbon outside the star to make you.
