Star formation starts in a nebula.
A nebula begins to contract due to gravitational forces overcoming the pressure from its internal gas and dust. As the material within the nebula begins to clump together, the gravitational attraction increases, leading to further contraction. This process can be triggered by external factors such as shock waves from nearby supernovae or collisions with other clouds, which can compress the nebula and initiate star formation. As the nebula contracts, it can lead to the formation of stars and planetary systems.
Stars, planets, solar systems, many objects in space can start as a large unstructured nebula of gas and dust, which can coalesce into massive objects under gravitational influence.
I have no idea. If a star is born within a nebula, how or why would it be compelled to leave it, since the gravity of everything inside the nebula would seem to hold it in there? So it doesn't make sense that a star like the sun would ever leave the nebula. Of course there is probably an explanation, but not one that I can find online very easily
A solar nebula begins to form when a cloud of gas and dust in space collapses under its own gravity. This collapse can be triggered by a nearby supernova explosion, a shockwave from a passing star, or other disturbances in the interstellar medium.
A nebula comes first; it is a large cloud of gas and dust in space. Under the influence of gravity, regions within the nebula can collapse to form a protostar. As the material falls inward, the protostar heats up and begins the process of nuclear fusion, eventually leading to the formation of a star.

begins to collapse under its own gravity due to a disturbance, such as a shockwave from a nearby supernova. As the nebula collapses, it heats up and the particles within it start to come together, initiating the formation of a protostar.

No, a nebula is a place where stars are born. Stars and clouds are very different.
