The ‘Big bang theory’ describes the origins of the universe. Before there could be life on the Earth, there desired to be a planet and universe to have that life. Edwin Hubble discovered that the universe is growing. From this rate of expansion, scientists were capable to find out that the universe began from a single point of compressed gasses 15 billion years past. The explosion of that point of compressed gas outward is the ‘Big bang theory’. From that explosion stars were made and over time space debris and in the end planets (we are talking about 15 billion years here).

The ‘Primordial soup’ is the mixture of gases and elements which are thought to have begun life on Earth.
