Spectral analysis of various distant stars and galaxies showed a Doppler effect that was indicative of an expanding universe, which is exactly what one would expect if the universe had been created in a huge explosion. Since then, there has been a great deal of other astronomical observation that is consistent with the Big Bang Theory. It is very solidly confirmed.

How do they know the big bang theory happend?

They didn't; the big bang theory is just an idea or a theory, not a fact. The empirical evidence that our Universe was, 13.7 billion years ago, much more dense that it is now, is overwhelming. No other explanation even begins to explain what we observe in our Universe. Saying the Big Bang is a "just an idea or theory" is like saying gravity is "just an idea or a theory, not a fact."

How is gravity related to the big bang theory?

Largely by being not related. The Big Bang theory doesn't really say anything at all about gravity.It's kind of distantly related through the "Theory of Everything", but the problem with this is that there is no Theory of Everything yet (actually, the situation is worse; there are multiple Theories of Everything, and we have no idea which is correct, or indeed if any of them are).
