1) The "Big bang theory" explains the origins of universe. Before there could be life on Earth, there required to be a planet and universe to consist of that life. Edwin Hubble discovered that the universe is expanding. From this rate of expansion, scientists were able to find that the universe started from a single point of compressed gasses 15 billion years ago. The explosion of that point of compressed gas outward is "Big bang theory". From that explosion stars were formed and over time space debris and eventually planets
The "Primordial soup" includes the mixture of elements and gases which are thought to have started life on the Earth.
