4,500,000,000 years ago Earth congealed from atomic elements of a star that exploded.
It was highly radioactive and extremely hot. The atmosphere of gasses had no free oxygen and there was no water on its surface.
The atoms of the new planet moved randomly and very fast.
There was no life on Earth for an estimated 1,000,000,000 years.
The same atomic elements that formed the Earth 4 billion years ago are still here, but they are cooler and re-arranged into different patterns of motion.
The atmosphere has a different mixture of gasses. Hydrogen and oxygen atoms have joined to form water distributed as clouds, oceans, lakes and rivers.
The carbon, hydrogen, oxygen and nitrogen and many other atoms now join in special ways to form life.
The atoms creating you, and every other living being, the land, oceans and atmosphere today are the same atoms that congealed from atoms blasted into space from the exploding star 4.5 billion years ago.
To focus on this true fact, look around and think about everything you see today being the same atomic elements, the same carbon atoms, hydrogen atoms, oxygen atoms, nitrogen atoms, that were around you just before you sat down to read this.
The atoms have not changed, not in five minutes, not in 4.5 billion years.
The atoms are in constant motion and are now moving in different patterns than they were a few minutes ago or billions of years ago, but they are the same atoms.
