The statement, <em>“Bacteria set the stage for other life forms to evolve on earth” </em>was made probably because Earth was populated exclusively by single-celled organisms (Archaea and Bacteria) at the time that it was oxygenated, and only one of these can perform photosynthesis that separates a water molecule and results in oxygen gas, which is called Cyanobacteria, which has a blue-green color that comes from chlorophyll. Today, Cyanobacteria can practically be found everywhere on Earth, possibly in the soil right outside your door, and still play a vital role in producing the oxygen that we breathe. Another reason could be, billions of years ago, single-celled creatures had the planet to themselves. Then, they established different ways for cells to share and communicate resources.
