The material that is currently in the Universe started something like 13.8 billion years ago, very close together, very dense, and very hot. It started expanding (space itself expanded) in an event called the Big Bang. Eventually, the material became galaxies, stars, etc.
The Universe has an age estimated to be about 13.8 billion years.
