....if nothing ever existed, nothing could form and exist.....i can't think of a way to explain it better in my head..but i know what i'm trying to say....there must have always been something....how could a planet have ever formed if there wasn't space for it to form and dust to produce the material needed to form a planet. how could the dust have formed if there wasn't a planet to explode, or a meteorite/astroid to hit a planet and well we all know what happens when they're big enough....
