Throughout the universe, the vacuum has energy. As we know from the equation E = MC2, energy can be converted into mass and vice versa. Sometimes, particles arise in the vacuum. Usually when this happens, there is a particle and an antiparticle that quickly destroy each other. But sometimes this doesn't happen right away, allowing for newly-created particles to interact with the real world.
It's possible that our universe could have arisen as a quantum fluctuation in the vacuum.
