Why are stars often found far from their birthplace in nebulas?

[Jøhn]

To my understanding, all stars are "born" in nebulas, however, if this is true, why is it that so many stars are so far from nebulas? Including our own sun.

 

[Chronos]

Primordial gas clouds, from which stars are ordinarily formed, are not the same thing as most nebula - which are more often the result of exploding stars. Newborn stars efficiently consume their mother clouds then give them a 'kick' when they ignite. In rich gas clouds, this often leads to starburst activity - where rapid star formation in a local region occurs. This rapidly depletes the nursery cloud. The best known nearby stellar nursey is the Orion nebula.
