A Short History of Life on Earth
The story of YOU is more beautiful and complex than you can ever image!
Many scientists believe that our universe started with a "BIG BANG" or a "BIG BANG-LIKE" event. The universe we live in was created by some type of BANG that contained all of the subatomic particles needed to make matter. This event was so huge, that we can still detect the echo of this energy in the form of Cosmic Microwave Background Radiation!
In the beginning, the early universe was too hot for atoms to form. As the subatomic particles continued to travel further away from the site of the BIG BANG, they cooled and the first atoms formed.
