The nebula theoryi think it's the passing star theory
The Big Bang Theory
I think it is the big bang theory, big crunch theory and i don't know the other one.
charles darwin prposed the 1st theory to explain the formation of life on the earth
There are six different stages in the condensation theory. These include the formation of a nebula cloud, the formation of a sun, the formation of planetesimals, the expulsion of gases from the forming sun, the growth of the planetesimals, and the formation of larger planets from planetesimals.
the nebular theory

That is called an accretion disk or a proto-Solar system.
The Big Bang Theory
The steps of the Nebular Theory consist of: The collapse of the nebula and formation of the protoplanetary disk and protosun. The condensation of planetessimals. The Accretion of planetessimals to form planet seeds. The Formation of Jovian planets through nebular capture and the solar wind of young sun clears away the remaining gas.

I think the solar nebula theory.
One theory is the Big Bang - after that, matter, including Earth, formed inside a solar nebula which later became our Sun.
The theory of the asteroid belt is - it was another planet that failed to 'gel' properly at the time the solar system was being created.
A theory of the origin and formation of the universe (the cosmos).
