The origin of life on planet Earth: A "cloud" falls from infinite space. Then, in the crust of the planet, as in the depths of the primitive oceans, could be observed the existence of a viscous element that covered the whole Earth. With this gelatinous mass, protoplasm was born. This matter, amorphous and viscous, with its condensation gave origin to the birth of the nucleus. The earliest inhabitants of Earth are albuminoid cells, amoebae, and all unicellular organisms that have multiplied in the warm waters of the oceans. These beings only reveal a sense: of touch, which gave rise to all others. source: www.thethinkingabout.blogspot.com
