Creation
The Earth was created along with all the other planets in our Solar System, approximately 4.5 billion years ago. The Solar System was created when pods of swirling gases and dust formed together and grew by attracting nearby particles of matter. These collections of dust and metal developed into the planets that now travel around our Sun. What made Earth able to sustain life for millions of years? How many other planets can or did sustain life in our universe? Scientists believe the Earth began as a waterless mass of rock. Heating of the Earth's interior caused chemicals to rise to the surface and form water and the gases of the atmosphere. The Earth changes continuously. Some changes take millions of years and others happen in minutes.
