One day there was an explosion in the sky known as the Big Bang. The Big Bang was the start to what we now call our universe. The Big Bang's temperature grew to be 9000 K. There was one scientist named Anne who was able to see this happen before her very own eyes in her dream.
The Big Bang was in charge of making matter, it should have made matter and antimatter equal, but that wasn't the case. Anne asked herself, "when was matter created?" and someone answered. It was Jake, another scientist who seemed to know all about matter! He told Anne that matter was created while the universe cooled.
Jake decided to invite Anne to his house so he could tell her more about the Big Bang. Jake told her that the first 3 atoms that were formed were hydrogen, lithium and helium.
He told Anne that the universe was expanding but Anne didn't know what he meant so he decided to explain it to her. "It's the increase of the distance between two distant parts of the universe with time."
When Anne asked Jake; how long ago the Big Bang occur, Jake was not able to answer her question. He himself did not know the answer. But then a peacock emerged out of nowhere.
He spoke and said "The Big Bang occurred 13.7 billion years ago." Both the scientists were amazed since a peacock was able to answer their question.
