Your question betrays a common misconception about the Big Bang -- that it was an explosion of dense matter into empty space. Despite many popular presentations that suggest this, it is SIMPLY WRONG. The Big Bang was an EXPANSION of space itself, and not into anything "out there," that took matter along for the "ride." Gas and dust did not form in our Universe till about 377,000 years after the start, so your question is even more bizarre.
If your question is, "What existed BEFORE the Big Bang?" the answer is simple: we don't know. Plain and simple, our understanding of our Universe breaks down when we get to "before." Indeed, we can't even define what "before" means at that point!
Gravity played a key role in causing dust and gas to come together after the Big Bang. As matter expanded and cooled, small variations in density led to the aggregation of particles due to gravitational attraction. Over time, this process resulted in the formation of stars, galaxies, and eventually planets.

The Big Bang Theory is a scientific explanation for the origin of the universe. It does not specifically pertain to the Sun. The Sun is a star that formed billions of years ago from a collapsing cloud of gas and dust in our galaxy, not from the Big Bang event itself.

Hmph. The Big Bang theory did not form the sun. The big bang formed the elements hydrogen, then hydrogen began to create helium. Then stars were formed out of these two elements and that is how our sun was created.
The big bang. Well, I'm not trying to be a smart Alec here, but the big bang didn't necessarily do that. The source is actually from giant clouds of gas and dust. While the sun takes away the hydrogen, it kicks the dust out.
There were no gas clouds prior to the Big Bang. Indeed, there were no atoms, no sub-atomic particles, and no quarks -- all of these came into being after the start of the Big Bang. What was there BEFORE our Universe started to expand? The answer is simple: we don't know.
The Earth was made long after the Big Bang, since the Big Bang occurred around 13.7 billion years ago and Earth is about 4.5 billion years old. Basically after the Big Bang, energy was converted into matter and the Universe was filled with clouds of hydrogen and helium gas. These clouds would coalesce through gravity to form galaxies and stars. One of these stars, our Sun, would form in the Milky Way galaxy. There would be a disk of gas and dust orbiting our Sun, from which Earth would form. For more info see the related questions below
The Big Bang theory is the leading explanation for the origin of the universe, suggesting that it began as a extremely hot and dense point roughly 13.8 billion years ago. The Earth formed about 4.5 billion years ago through the accretion of dust and gas in the solar system as it cooled down.
A galaxy is a big assembly of stars, gas, and dust that is held together by gravity. They come in different shapes and sizes and contain billions to trillions of stars. Our own galaxy is called the Milky Way.
Gravity. Note that mostly it wasn't all that dense.
A lot of distinctive smelling natural gas.
