Detailed explanation-1: -A wide range of empirical evidence strongly favors the Big Bang event, which is now essentially universally accepted. Detailed measurements of the expansion rate of the universe place the Big Bang singularity at an estimated 13.787±0.020 billion years ago, which is considered the age of the universe.
Detailed explanation-2: -The Big Bang was the earliest known event in the universe. We can trace the history of our universe back about 14 billion years, to a fiery period known as the Big Bang. At that time, the universe was extremely hot and dense.
Detailed explanation-3: -But more than 13 billion years ago, following the big bang, the early universe was hot, and all that existed were a few types of atoms, mostly helium and hydrogen. As atoms combined to form the first molecules, the universe was finally able to cool and began to take shape.
