Amazing Facts About Earth:
Strong evidence suggests that the universe began with the Big Bang about 13 billion years ago, and two thirds of its history passed before our own solar system was formed. During this time, stars evolved and died, supplementing the basic hydrogen, helium, and trace of lithium that the universe began with and providing more complex atoms such as carbon, oxygen, silicon, magnesium, and nitrogen. The way Earth was formed allows for its many unique traits that have developed and will develop during its life.
