Around 4.5 billion years ago, stars that had previously formed burst, giving rise to the Earth. Some of these stars were large enough to synthesize iron, which is found in meteorites, but a significant portion resides at the Earth's core, which is why we have a protective magnetic field.
In truth, water is found in comets and may have been the genesis of water on Earth. The cosmos began 9 billion years before the earth and our solar system, thus all the components on our planet came from old stars.
The components that can be produced by smaller suns, yet they are still greater than our sun, are what make up life in the cosmos. The end-of-evolution explosion of suns has been observed several times throughout history as a brief burst of brilliance followed by an expanding cloud where the star had been. We are comprised of star material, as Carl Sagan once stated!
The hydrogen was gathered by stars in the early cosmos, squeezed by gravity, heated to the point of nuclear fusion, and then transformed into heavier elements to create the Earth. The heavier elements were created, the faster the star went through its life cycle, and the sooner it burst, launching all those components into space in a powerful explosion. That provided us the building blocks we needed to begin the evolutionary process, which is how we now understand it.
Only lithium and helium are produced by our little sun.
Few people still believe in "Creation," an ancient Hebrew tale that dates back more than 2500 years and attempts to explain where we came from, and because it is merely a fiction, it cannot be taught in contemporary classrooms. Well-researched evolutionary science provides insights into many inherited disorders, which is far more helpful.
The ability to use tools to see components develop in far-off suns is a fascinating topic.
