Big Bang Cosmology was first proposed (although not by that name) in 1930 by Jesuit priest Georges LeMaitre. It became the standard cosmology after the discovery of Cosmic Microwave Background Radiation in 1964, and all alternatives to BBC are now almost pseudo-science.
The Big Bang is estimated to have occurred around 13.8 billion years ago, based on scientific measurements and observations of the expansion of the universe.
What explosion And if you are talking about the Big bang it happened about 13.7 billion years ago
The Big Bang theory was proposed (happened) in the middle of the 20th Century.The theory, and the work exploring it, suggest that the Big Bang happened about 13.7 billion years ago.
The current estimate for the initial expansion of the universe dubbed "The big bang" occurred about 13.7 billion years ago.
According to the believes of physics and the big bang, we know that the big bang was both big and a bang. Since we are still receiving radiation from the big bang, So considering that factor I would say that it was big and a bang. What do you believe?
The big bang occurred approximately 13.7 billion years ago.

The Big Bang.
The event that marks the beginning of the universe is the Big Bang. This was a cosmic event that occurred about 13.8 billion years ago, creating the universe as we know it today. The Big Bang theory is widely accepted by scientists as the most plausible explanation for the origin of the universe.
The Big Bang! Space-time did not exist before the Big Bang so there can be no earlier events.
The most used expression is big bang.
Whatever planet you have in mind, if it's in the Solar System, it was 'created' during the big-bang. The big-bang occurred 13.798 ± 0.037 Billion years ago.

The Big Bang is estimated to have occurred around 13.8 billion years ago, based on observations and measurements of the universe's expansion and the cosmic microwave background radiation.

There is no data on what might have occurred before the Big Bang. There is not even a consensus on whether the phrase "before the Big Bang" is valid to begin with.That having been said, cosmologists now strongly favour non-cyclical models of the universe; the hypothesis that the Big Bang might be a continuation of the cosmos following a preceding Big Crunch is very much out of favour.
