There are more than just four observations that Big Bang Cosmology easily explains, but alternatives to BBC completely fail to do so.
1) Hubble Red Shift
2) The existence, isotropy, and spectrum of the Cosmic Microwave Background Radiation.
3) The ratio of hydrogen to helium in all parts of our Universe.
4) The ratio of long-lived isotopes to their decay products do not allow any of the former to have existed more than 10 billion years ago.
5) No white dwarf stars have been found older than 10 billion years.
6) Quasars are observed far from us, but none are close.
No
It depends, because some might say 'scientists'. But not all scientists believe in this theory. Also, there are those who believe in a similar idea to the Big Bang, but it is not refered to as 'The Big Band Theory.'
The Big Bang theory was proposed (happened) in the middle of the 20th Century.The theory, and the work exploring it, suggest that the Big Bang happened about 13.7 billion years ago.
Scientists who study Big Bang Cosmology are (generally) referred to as cosmologists.
Real scientists do not "gather evidence in support of" any theory. The technical term for that kind of thing is "cherry-picking". Real scientists build a theory to explain the evidence that they have already gathered, and then test the theory to see whether it holds water. The easiest, fastest way to make sure that you are regarded as a wingnut by real scientists is to adopt or invent a theory, and then spend your time trying to prove it.
Discard it all.
The Doppler effect and background cosmic radiation are the big ones.

No
The Big Bang theory isn't a mystery: the scientists working on it know exactly what they mean by what they say.
Before the Big Bang theory, many scientists believed that the universe was static, or infinitely unchanging.
Answer: Certainly not.
