And that is where you are wrong. So obviously youre an atheist and you believe in the theory of evolution. I'm guessing there. Just for a second imagine yourself as not an atheist, not a believer, but as someone who stands on neutral ground. Just look at the theory of evolution. One theory is that the crust slowly came to form... out of nothing. Then it grew into the world, the galaxy grew around it, the Sun popped out of nothing and BANG! everything is created in perfect harmony to allow for humans to live, seasons to work, tides to work, etc. Does that sound correct?
Are you trolling? Because if you are not, your understanding of the steps of how the universe progressed is flawed.
First of all I need to mention that evolution of life is different than how the universe formed. You can believe in cosmology and its hypothesises and not believe in evolution. They are two different things.
Second, no the Earths crust didn't come from nothing.
Let me try to explain. The big bang theory is a derogatory term. People constantly say there was a point in the past where a very small highly dense point exploded and expanded creating space.
But let me fill this in with, nothing exploded. Sure there was a singularity that had nothing outside it. It didn't explode but instead it inflated. Expanded and continues to expand.
Now there were no stars, planets, asteroids in the beginning for hundreds if millions of years because the young universe was TOO hot for atoms to form. Only after the universe cooled down did atoms form.
These first atoms were mostly hydrogen and helium atoms. The universe was not uniformly equal so there were dense regions which the first super massive stars formed. They were huge and burned fast. Probably only existing for a few hundred million years before they collapsed to form the first massive black holes.
These massive black holes pulled in more surrounding gas due to intense gravity fields. When this happened they started to form galaxies. Which densely compresses the hydrogen gas creating stars.
Our sun, is probably a third or fourth generation star, meaning it was created when stars before it, exploded spewing out its elements into space.
Stars compress atoms together due to their intense gravity and heat. This process is called fusion. Combine two hydrogen atoms, you get helium. You can also compress two helium atoms together which form Beryllium. You can also compress one Beryllium atom with another helium atom to form a Carbon atom.
Anyways stars die and when they do they explode sending heavy elements scattered into space.
Our sun, the Earth and the rest of the planets plus the iron in your blood, the calcium in your bones, the water, everything you see was once inside a star that exploded billions of years ago.
The Earth firmed slowly by this debris of rock and gas. Slowly clumping together over millions if years. In fact the Earth is still getting bigger, the Earth gains five tons of new material every year.
So no the Earth didn't magically arise out of nothing. But if you really want to get technical, atoms are mostly made of nothing.
