Billions of years ago, the Earth was nothing but a lifeless rock completely covered in super volcanoes. Over time the steam from the volcanoes formed our atmosphere, which prevented any further steam and gasses escaping into space. Therefore the steam fell as rain, which over a course of thousands of years, formed oceans.
Eventually, bacteria began to spring to life, since water equals life. It is possible that this bacteria was not formed on Earth, but instead came from outer space, because scientists have proved that meteorites that crash into Earth do hold small traces of bacteria. However most believe that the bacteria was created on Earth itself.
Over a course of millions of years, this bacteria evolved into jelly-like creatures, which formed into small fish, then into large fish. The large fish then developed legs and walked on land like crocodiles. These crocodile-like reptiles then evolved into dinosaurs.
