Evolution 1

"And lastly, a thought for the right-wingers out there: At some point half of you was an egg in your Mother’s womb. That egg existed in her body from the day she was born. And a long, long time ago, she too was an egg in her Mother’s womb, who had that egg ready for use from the moment she squirmed out of your Great Grandma’s nethers. The point being, technically speaking, there’s no break in the chain of existence, no time when you are not a life form of at least the most rudimentary sort. Your family, at least on your Mother’s side, could theoretically be considered an immortal, constantly-regenerating organism. Of course that would make men, whose sperm has to be created years after the moment of birth, just disposable donors here to fuel the everlasting fire of womanhood. You go girls!" -Cracked.com

I'm always amazed when I think about life and the beginnings of where us as a species and us inhabitants of earth originated. From my limited knowledge all human life originates from one person who lived thousands of years ago who evolved from a proto species of ape who evolved from a proto species of mammal who evolved from a proto species of fish who evolved from a single celled organism that evolved out of amino acids creating chemical reactions in the primordial soup 3.5 billions of years ago. This all not being possible without the help of water. There are many theories on where water on earth originated I dont know which ones are the most trusted. It seems all we can do is speculate for now. According to wikipedia the main theories are-
* The cooling of the primordial Earth to the point where the outgassed volatile components were held in an atmosphere of sufficient pressure for the stabilization and retention of liquid water.
* Comets, trans-Neptunian objects or water-rich meteorites (protoplanets) from the outer reaches of the asteroid belt colliding with a pre-historic Earth may have brought water to the world's oceans. Measurements of the ratio of the hydrogen isotopes deuterium and protium point to asteroids, since similar percentage impurities in carbon-rich chondrites were found to oceanic water, whereas previous measurement of the isotopes' concentrations in comets and trans-Neptunian objects correspond only slightly to water on the earth.
* Biochemically through mineralization and photosynthesis (guttation, transpiration).
* Gradual leakage of water stored in hydrous minerals of the Earth's rocks.
* Photolysis: radiation can break down chemical bonds on the surface.

I kinda like the comet one but that's just me. Now all life came from single celled microbe like organisms in water which wouldnt be here without the planet earth itself.

The planet earth originated when our solar system (which was comprised of a cloud of dust and gas spiraling around in a giant disk shape) began to spin at such a rate that all the mass contained within collected in the middle of this giant disk. sort of like when you toss a penny into those spirally things. I have no idea what they are called but you get the idea. all of this mass began to heat up because of moving so rapidly and started to form proto planets from the debris of the crushing mass. all of this matter heating up in the center had no where to go and was getting extremely hot. "nuclear fusion of hydrogen into helium began, and eventually, after contraction, a T Tauri star ignited to create the Sun." 4.54 billion years ago our planet was born.

Now all of this planet making business came about because of the debris left over from the big bang the start of the entire story of all of our lives.

In conclusion, every single person place thing constalation planet star gas or microbe originated from the same source. We are all connected, we are all one being one organism one life. I find it fascinating.
