Where on earth did life first appear?

Life on planet Earth, according to scientists, appeared about 3.5 or 4 billion years ago. The origin of life took place initially in water (aquatic environment). This life was not at all what it is now. First, unicellular organisms appeared. They were very primitive. Only over time did they learn to release oxygen. Over time, unicellular organisms developed and transformed into multicellular and colonial ones. At that time, numerous volcanoes were still actively erupting on the planet, releasing vapors, ash and lava. There was not enough oxygen on the planet for life to go to land. Therefore, the existence of life outside the water was not possible.
