The Big Bang This was the birth of all the planets. The Big Bang occurred about 14 billion years ago. This is how all the planets and our solar system was formed.

The Forming Of our planet Planet Earth was one of the planets that were formed during the Big Bang. This happened about 5 billion years ago. Scientists think that volcanic outgassing formed both the atmosphere and the ocean.  However this atmosphere contained no oxygen at all.

The Earth was molten in the beginning of these stages and would soon be cooled and transformed into solid layers. This allowed water to exist on the surface.  These were the later stages of the Hadean Era.

The Formation of life on earth This was also called the Archean and Proterozoic Eon. These were the beginning stages of Early Life on the Planet. The life that was included were multicellular organisms A lot of these organisms were aquatic.
