More precisely, the particles appear from what is known as a false vacuum. This is an actual state of the universe, but a state where there is nothing (no particles, etc) in the universe.
Perhaps the strangest part of this for the ordinary person is to think of 'nothing' as being a state of the universe where the laws of physics apply.
Yes, we need the laws of physics and we need a state of 'nothing'. Some people would claim those constitute 'something' as opposed to 'nothing', but let's face it, God didn't create from 'nothing' since God was supposed to be there.
The main difference is that physics doesn't assume a deity, but does assume laws of physics. But we know laws of physics exist.
