    There are ways for things to come from nothing in quantum mechanics. Positive/negative particle pairs can pop into existence because their average energy is 0. They’re typically very shortly lived though. It’s possible it didn’t come from anything and just was. Time is also part of space-time, so there wasn’t a “before” most likely either
