Some think that the clouds were left over from the big bang, true maybe.
But then why weren't they developed as stars/Galaxy's long ago in the cosmic dark age like most s and gs. now the debate is about what happens to the material that black holes swallow up. some think it gets deposited in the next dimension and others think its strewn across thousands of light years of space. making it ready to start the whole process again. then another is to think it just ends up as nothing because you can't have something without nothing and this is where we start getting lost and start headbutting the walls. please add your own views on this matter. don't bother answering if You haven't got anything decent to say
 
Some of those dust clouds did use to be stars, they just didn't live very long as they were so massive. Many nebulas (e.g. the Crab Nebula) are the result of supernova explosions, where a star basically spews its guts out into the cosmos. Also bear in mind that the dust you see in space is VERY tenuous. It looks very thick in astronomical photos, but that is because we are viewing from a great distance. In reality, nebulas have fewer atoms per square metre than the best laboratory vacuums we can create here on Earth.

Also bear in mind that if you have a dust cloud that has little or no motion, it won't necessarily begin to form stars. The reason why stars spin is because they formed from spinning clouds of dust. You need something to set that dust cloud in motion (e.g. a supernova) in order to create a star.

We have no idea what happens to material that falls into a black hole. Your guess is probably as a good as anyone elses. It may well come out into another universe, via hypothetical "white holes". Perhaps our Big Bang singularity was actually a white hole, fed by the black hole from another universe?
