Usually from the collapse of a massive star. It isn't quite clear how a supermassive black hole is created; it is possible that it also starts as a stellar black hole (a hole resulting from the collapse of a star), but it isn't quite clear how such a black hole can get so huge in a relatively short time.

Black holes are the result of the gravitational collapse of a large star.
Black holes are the result of a large star that has collapsed.
Bursts of light from black holes are the result of the accretion (or "consumption") of matter by black holes. Quasars are an example of this.
A dead or dying star will start to create a black hole
The relevant magnitude is mainly the black holes' mass. Since black holes are the result of collapsing stars, yes, there are black holes with the mass of a star.The diameter is usually taken as the diameter of the event horizon. This diameter is directly proportional to the mass; a supermassive black hole such as Sag A* has a diameter comparable to that of a large star.
If space men are brave enough they can go far far far away into space and that is probably find one.There are black holes all over the galaxy. They result from the collapse of larger stars. The closest known black hole is a few thousand light-years away, but there may well be black holes nearer to us.There are black holes all over the galaxy.

1) It isn't known whether aliens (in the sense of extraterrestrial life) exist. 2) It isn't known whether wormholes exist. 3) No aliens are required to explain black holes; black holes form quite naturally as a result of the collapse of a massive star.
Whether it "needs" them or not, they are there - an inevitable result of a Universe dominated by gravity. Supermassive black holes may have an important role in star formation, but this is still an area of active research.
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
The only known mechanism to produce a black hole is the gravitational collapse of an object that has at least 2-3 times the mass of our Sun. However, it is considered possible that the enormous densities right after the Big Bang may have resulted in some black holes; for more information, read about "primordial black holes".
No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.
Black holes do not die but they can evaporate.
