Several billion years later, the earth became so violent as to explode loudly. In time the water vapor was produced. Water was fundamental to the development of life. Many millions of years later, small plants began to appear on the surface of the water, filling the oceans and seas with oxygen. Later reptiles turned up for the first time. The disappearance of dinosaurs made possible the rise of mammals which gave birth to young baby animals. Finally clever animals have, in their turn, become the most important animals on the planet. They spread all over the earth, putting too much carbon dioxide into the atmosphere which prevents heat from escaping from the earth into space.
