We Are Children of the Cosmos

Bang, bang—we were once stars; every atom in a human body was once inside a celestial star. Elements, such as atoms and even ions, once belonged to stars—the trees, planets in our solar system, and us. Stellar nucleosynthesis produced elements such as carbon, oxygen, silicon, and iron; the stars are our ancestors.

Scientists still believe we are made of star stuff. The environment outside our solar system was produced even before our solar system formed—this was inside the stars that existed long ago. On behalf of the National Aeronautics and Space Administration (NASA) Science, they reported Earth was formed 4.54 billion years ago, made from stellar dust, and parts long before homo sapiens existed.

In accordance with Space (an astrology-based website), their study proved that 150,000 stars in the Milky Way shared about 97% of the elements in the human body. Nonetheless, the Royal Society of Chemistry identified approximately 60 chemical elements in the human body that originated from supernova explosions.

Following NASA Universe, about 99% of visible matter in Earth was made in a plasma state—the universe began with a Big Bang, making it possible to make life. On the other hand, this helped scientists to research more about the origin of life, and the evolution of stars—humanity is within stellar.

Descendants of Stars.

“The cosmos is within us. We are made of star stuff. We are a way for the universe to know itself," stated by Carl Sagan.

We are within the universe; the universe is within us; we carry the ashes of stars, and we are stardust.
