There's net negative entropy involved, though. That's **** weird, at the very least, and certainly not "net nothing."
1) The second law of thermodynamics contains the implicit assumption that it can be broken.
2) Entropy itself is a property of matter based on temperature, which is also a property of matter. Prior to the Big Bang, there is nothing. As matter is anything which is not nothing, we have no entropy and so entropy, like time, has no meaning. Just as "before the Big Bang" has no meaning, because there is no time and no universe to exist, entropy calculations involving a span of time that includes the Big Bang are also meaningless. The second law of thermodynamics that we know only holds
after the net negative entropy that you find problematic. It could be possible that we discover a law of conservation of entropy, whereupon the net negative entropy stemming from the Big Bang is eventually canceled by all of the thermodynamic processes over the lifespan of the universe, but that's hard to take data for as it involves the universe ending.
3) Speaking of the possibility of a law of conservation of entropy, entropy is often referred to as the arrow of time. We know time to proceed forward because of entropy. Suppose the Big Bang is the positive charge at the center of this electric field:
Our universe is the one where time flows forward in the +x direction. Could there be another universe that exists on the other side of the Big Bang in which time flows backwards in the -x direction, one in which entropy would always have to decrease with each thermodynamic process? Their sudden net positive entropy from the Big Bang would be just as problematic as our sudden net negative entropy (which would be equal in magnitude). Only, they aren't two separate universes. They are one universe, and both move in opposite directions along the same time axis. It's not such a bizarre notion. We can easily wrap our brains around moving backwards through time. Harder to conceptualize is the notion of time flowing "up" or "down," but the t→
it transformation accomplishes exactly that, so it's hardly something that has never occurred to us might be possible.
