The very first sphere is the geosphere. The geosphere is made 4.5 billion years ago. The minerals used to make the geosphere came from space. More than 4.7 billion years ago space was filled with grain sized meteorites, these meteorites started clumping until it became 3/4 of the earths size then it collapsed and a chunk of earth went flying to space and became the moon.
The second sphere is the atmosphere. The atmosphere was made when the earth started rotating faster. After that, chemicals in earth started spreading making air but, filled with toxins and harmful gasses to life. All there was in the atmosphere back then was just full of deadly gasses and the suns radioactive rays that will melt you into a puddle of flesh and blood.
The third Sphere is the hydrosphere. The hydrosphere made life possible and turned the whole entire earth into a slime ball filled with burning rocks within 300 million years. the water of the hydrosphere came from the meteors that hit earth. Those meteors have ice in them and when it landed onto earth it turned into water.
The fourth sphere is the biosphere. The biosphere was made by all the other three spheres, it is also the cause of the earth turning into a slime ball filled with bacteria and micro organisms. The biosphere started inside the meteors that hit earth. inside the meteor are billions and millions of bacteria and cells, if the meteor hit earth and a single cell just the single cell that survives will change the whole entire earth within a few million years (20 million years should be enough).
