Nebula are an accumulation of gas particles.
Bearing in mind that there untold billions of atoms in the cosmos.
Any two atoms have a gravitational attraction between them. they come together, thus attracting more gas particles by gravitational attraction.
These gas particles become so crowded that they begin to glow, (the nebula).
The analogy, is a dance hall/disco; maybe two people will statr to dance. Eventually a lot more people arrive on the dance floor, and it becomes hot and crowded.
Under further gravitational attraction these hot crowded gas particles keep accumulating into a hot glowing ball. Because partiucles are now so crowded nuclear fusion starts, and releases energy. Hence a Star/Sun.
Because this process takes billions of years we do not instantaneously see it going on.
NB All stars are nuclear reactors in space.

Emission nebula glow and reflection nebula reflect the light form other stars
What two things cause nebula gases to begin burning?
When a star uses up all of it's fuel one of two things can happen: either it explodes as a supernova, releasing large amounts of gas and dust into the surrounding space; or the star will expand into a red giant (which will happen to our sun) and release it's outer layers gradually in the process. Both of these processes will produce a nebula.
