Origins of Life

Amino acids can be found within meteors and other stellar objects. Amino acids make up proteins which are the building blocks of life and can be altered under extreme conditions to create larger and more complex amino acids. An extreme condition occurred when Meteors hit the Earth, which occurred in Earth's early history. There is an unexplainable question between how microbes were created from amino acids. Microbes got started in extreme conditions and may have had their building blocks from outer space. After the bombardment 3.5 bya microbes started photosynthesizing and allowed green slime to take over the earth. The oxygen as a waste gas created an ozone that allowed complex life forms to take hold. The oxygen level rose from less then 1% to 21% which allowed complex life forms to take hold.
