Please read below.

Explanation:

We have, however many hypotheses that could explain it, such as string theory or m-theory, the problem we have right now is that all the predictions these ideas make about the universe are impossible to test with our current technology. You see, all scientific models make predictions and we can prove or disprove them by going out and making observations that confirm or deny that model.

  • What was there before it?

Same as above, we have models that could explain it, but the observations are beyond our tech so far.

  • What is some evidence for it?

In the 1920s Edwin Hubble (the telescope was named after him) discovered that all galaxies are flying away from us, and the further away a galaxy is from us the faster it is going away from us. This proved the Universe was expanding. Meaning it must have been smaller early on. This begat the Big Bang Theory.
There are many cosmological observations that corroborate this, and one of the best, which was predicted by the theory itself, is the Cosmic Microwave Background.

  • Why do some people not agree?

Overall the school system has done a poor job of communicating the science to the people. The media also doesn't help as it is sensationalist and misrepresents the issues most of the time, leading to people distrusting science. Religion also plays a part in it as science disproves some of the stuff written in their holy books, so they (true to their doctrines) truest blind faith over knowledge.
