Life as we know it evolved from bacteria, the main source in which life was created after billions of years. Bacteria allowed single celled organisms to form and throughout time we developed multicellular organisms that then produced/ created waste which was known as oxygen. The oxygen then allowed us to build an ozone layer that protected animals and plants from the harsh uv radiation the sun was creating. That’s how many species evolved onto land. The oxygen also allowed the water to turn that bright clear blue we see today but thousands of years ago the water was a murky green. The …show more content…
