cyanobacteria also called blue-green algae is thought to be one of the first ever photosynthetic organism...prior to the evolution of photosynthetic organisms theoxygen percentage of the atmosphere was 0% and as we all know without oxygen (O2), ozone(O3) cannot form, and without ozone there can be no atmosphere. Photosynthetic organisms allowed for the formation of oxygen and brought oxygen levels to the percentage it is today (20% a significant increase from 0%) as a result ozone was able to form and ultimately the atmosphere emerged.
