What is is earths evolution?

The most popular scientific theory states that earth was once a Porto planet, a planet that is like a baby. a large asteroid [left overs from the sun] soon gained gravity that pulled more asteroids towards it. in a few million years, the large asteroid will become red and be filled with lava. volcanoes erupted that formed clouds with water then water filled today's ocean. the rest of the volcanoes made large islands that became Pangaea then Pangaea becomes today's continents. of course earth developed an atmosphere then clouds formed. the first animal was a bacterial that released methane in to the atmosphere. later oxygen releasing Bacterial developed and killed the methane releasing bacterial. then fish evolved, then land animals [small] then dinosaurs, then mammals, the probably Porto humans or early humanly creatures, then homosepicans, then caveman, then today's humans.
