Don’t humans have something like stardust or something like that in their blood? Or body? Like, I think I heard somewhere that humans have something in their blood that otherwise only stars can produce.

It’s not just in the body, but it is the body.

Stars are element factories – they make all the different atoms that make up stuff in the universe. The planets, the water, the living beings, etc. The reason why the star/sun is so hot is because of all the chemical reactions happening when new elements are created from old elements, and they are layered in the star like a jawbreaker with the lighter elements at the top and the denser ones at the bottom.

Our star is made of some of our favorite elements that humans happen to be made of: Hydrogen, helium, lithium, beryllium, boron, carbon, etc.

Eventually, when a star dies it turns into dust, and that dust will gather into other celestial bodies like asteroids and planets. Humans ‘came up from the dust’ on Earth essentially. Humans are made of elements from the Earth (our bodies being built by what our natural mothers eat, and then eventually what we eat ourselves), and the Earth is made of stardust from whatever was here before Sol, Earth, and the other planets and celestial bodies.

So yes – Humans are stardust. Everything is stardust. 🙂
