According to Johannes Kepler, he thought when posed with the question, when was the universe created? he calculated it was formed in 4977 B.C. on April 27. Johannes Kepler was a German mathematician and astronomer who was thought to be the founder of modern science and is most commonly known for his theories explaining the motions of planets.
Kepler published works in the early 1600 that didn’t get a great deal of recognition during his lifetime but were referenced by Sir Isaac Newton in producing his laws of gravitational force. His calculation of the Universes birthday is now widely recognised as being inaccurate after the ‘big bang theory’ was published in the 20th century and suggests he was about 13.7 billion years off.
