Explanation: 

Detailed explanation-1: -The Big Bang event is a physical theory that describes how the universe expanded from an initial state of high density and temperature. Various cosmological models of the Big Bang explain the evolution of the observable universe from the earliest known periods through its subsequent large-scale form.

Detailed explanation-2: -The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. Most astronomers use the Big Bang theory to explain how the universe began.

Detailed explanation-3: -It now appears that the universe began at an instant of time approximately 14 billion years ago. The three lines of evidence for the origin of this event are universal expansion, the cosmic microwave background, and the abundance of light elements.
