      To the best of our knowledge, it happened 13.8 billion years ago… a crazy long time ago.

      Before the Big Bang nothing existed, not even time! So the Big Bang happened at the beginning of time. And all the matter that there will ever be in the Universe was created in less than a second. It wasn’t until 300,000 years after the Big Bang that atoms began to exist, and a good 1 billion years after until stars formed. And as Yasmin said, physicists reckon it has now been 13.8 billion years since the Big Bang.
