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.
# Hydrogen gas, i.e. after the big bang, hydrogen formed, this with heat, formed planets, metals, galaxies, etc
Clouds of dust and gas.
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. 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.
Stars. That is how stars are formed. They form from nebulae.
Most of the nebulae that exist now are formed from the expelled remnants of dead stars. The gas that made up the original nebulae form with the Big Bang.
It depends on how much gas and water that contains in each cloud formed
The prevailing view is that stars form from the gravitational collapse of immense clouds of gas and dust in outer space.
the universe was created 13.7 years ago and is explained by the big bang theory. there were residual gases that formed and created the planets and the stars.
Stars are formed by hot clouds of gas and dust, named nebulas.
The Big Bang BIG BANG was formed in 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. Most astronomers use the Big Bang theory to explain how the universe began.
