Are humans star dust?

We Are Stardust—Literally. In this infrared image, stellar winds from a giant star cause interstellar dust to form ripples. There’s a whole lot of dust—which contains oxygen, carbon, iron, nickel, and all the other elements—out there, and eventually some of it finds its way into our bodies.

How was human born?

On the biggest steps in early human evolution scientists are in agreement. The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs.

Stars are like nuclear reactors. They take a fuel and convert it to something else. Hydrogen is formed into helium, and helium is built into carbon, nitrogen and oxygen, iron and sulfur—everything we’re made of. … So most of the material that we’re made of comes out of dying stars, or stars that died in explosions.

When was Adam and Eve born?

They used these variations to create a more reliable molecular clock and found that Adam lived between 120,000 and 156,000 years ago. A comparable analysis of the same men’s mtDNA sequences suggested that Eve lived between 99,000 and 148,000 years ago1.
