Nope, it requires proof. Evidence doesn't cut it because at the end of the day, every bit of "evidence" is simply speculation. Sure, you can say it looks good, and points to a big bang, but there is always that doubt, otherwise they would come out and say big bang is fact.
They cant say its fact because they simply dont know. Hence why it takes just as much faith to believe that something sprang from nothing as it does to believe in God.
You know, everything you say demonstrates you have no clue how science really works, and you haven't even tried to learn about it. Instead you blab embarrassing nonsense about "belief", and you are even failing the for-free education Fort Fun Indiana provides.
Belief has nothing to do with that. Whatever is not yet explained about the Big Bang (the origin of the universe) isn't settled by "belief". Rather, it's the physicists' next research program, as their understanding progresses toward the first trillionth of a second of the universe. "Belief" would mean they settle for some assumptions, and that's it, no evidence, no further research required. That is exactly the opposite of how science works.
Why, really, why don't you take a bit of time and read up on the matter? Start
here, for instance. Read it twice, if necessary, and cease embarrassing yourself already.
