Hydrogen and helium
Hydrogen and helium are the materials that could have been found in the giant cloud that formed the solar system.
Explanation;
According to the solar nebular theory, the Sun and all the planets of the Solar System began as a giant cloud of molecular gas and dust.
The theory further explains that that the giant cloud could have resulted from a passing star, or shock waves from a supernova, however, the end impact was a gravitational collapse at the center of the cloud.
The molecular cloud of gases included gases such as helium and hydrogen gases.
