Are people made of stars

Answer 1

Yes, we are "star stuff". People, and everything around us, are made of stuff that has been IN stars.

At the time of the Big Bang, the universe was made of mostly hydrogen, a little helium, and a tiny trace of lithium. The hydrogen collapsed under gravity to form stars. The energy of stars is nuclear fusion, which smashes light elements into heavier ones. At first, the hydrogen fused to make helium. After a long while, the stars would collapse into supernovas, and explode. The explosion would create even heavier elements, like nitrogen, carbon and oxygen, and even heavier elements like iron.

The iron in our blood, the calcium in our bones, and the nitrogen and oxygen that we breathe came from the supernova explosions of stars billions of years ago. Our atoms were blasted into space, and then fell into new solar systems, and that material became "us" - and every atom of the Earth, Moon and planets as well. In fact, we've probably fallen into stars and been blasted into space several times in the 14+ billion years that have elapsed since the Big Bang.
