    The first organisms on Earth are tiny microbes. They can inhabit extreme environments such as hot springs, and extremely frigid temperatures. There is a debate from what source these microbes originated. Some say it was from the chemical mixture of ancient earth while others hypothesize the source might be organisms from outer space.

    The general consensus is that ‘heterotrophs’ were the beginnings of life on earth. These one-cell organisms lived in the oceans and seas, and absorbed the amino acids and carbons that were being organically produced by the Earth. Amino acids, the ‘building blocks of life’, acted as a food source for these organisms.
