Quick Answer: Are We Made Of Stardust?

What percentage of stardust are we?

93%The human body is about 60% water and hydrogen only accounts for 11% of that water mass.

Even though water consists of two hydrogen atoms for every oxygen, hydrogen has much less mass.

We can conclude that 93% of the mass in our body is stardust..

How are humans made of stardust?

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.

Who created the humans?

God created people (Homo sapiens) pretty much in their present form at sometime within the last 10,000 years. People developed over millions of years from less advanced forms of life, but God guided the whole process, including our development. People developed over millions of years from less advanced forms of life.

What are we made of?

Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium. All 11 are necessary for life.
