It's not so much that we know there was nothing before it, but that we can't figure out what was before it.
No, in our current best-supported model of the universe (Lambda-CDM) the concept of “before” the Big Bang is meaningless. It is the apex of the spacetime “bell” from which everything emerged.
But something must have triggered the big bang. The model might not support this, but this only means the model is insufficient to describe what goes beyond our known universe.
Obviously God did it. /s
