Nothing and everything.
A very difficult question to answer.
It is an attempt by cosmologists to answer what is perhaps the most fundamental question.
Many things about such matters are not easily explainable. Some people turn to spirituality, and leave it to a god or gods, some others dig more deeply

True
Nobody knows for certain what happened before the Big Bang exploded, or why it exploded when it did explode. Astronomers have determined much of what happened back to the Big Bang, but, Nobody knows anything, about what happened before the massive explosion that started the universe we live in now, and for the last billions of years. There are countless unanswered questions about the pre Big Bang universe that might never be answered.
According to the believes of physics and the big bang, we know that the big bang was both big and a bang. Since we are still receiving radiation from the big bang, So considering that factor I would say that it was big and a bang. What do you believe?
It shouldn't be considered as being big (as in large) due to that the big bang would have comprised of everything within an unfathomably small point in space (Known as a singularity) that exploded outward in an expansion that created spacetime, which to this day continues to expand. Think of it like an expanding balloon and everything exists on the outside of said balloon.
We have no idea what it was that exploded in the Big Bang, but it probably was NOT "matter" in the sense that we think of now.
