Most likely the battery has insufficient charge to turn over the starter motor.
If you can start the car by jump starting from the battery in another vehicle then you know your battery is the problem. In that event it needs to be recharged or replaced if it will no longer hold power. It is probably the original battery in the car and typically these can give trouble in anything from 3 - 5 years depending on quality and a range of other factors.
