Are there any advantages of human beings? Humans have caused more irreversible damage to the Planet Earth than every other animal that ever lived here, ever...
However, we are a naturally evolved animal, just like all of the others. Gravity is only an advantage if you rely on it. Carbon dioxide is an advantage if you like it very warm and/or breathe it, it's a disadvantage if you breathe oxygen and don't like it too warm.
Basically, Black Holes exist as a result of the force of gravity increasing as distance between particles decreases... this means that the closer particle are, the closer they want to be.
They are of little use to us, that we can see - except perhaps for use as a gravitational slingshot. But I suspect that - for any form of manned transport, at least, that's not something which would appeal, should we even be a ble to get near to one.
No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.
No, we have not seen any evidence of a black hole in our solar system.
Hardly any. The nearest known black hole is at a distance of about 3000 light-years; even if one of the nearest stars were actually a black hole, it wouldn't be particularly dangerous.
An active black hole is a black hole that it by all manner of terms is "feeding". That is, it is accreting matter, or sucking matter into itself. Most black holes are dormant and don't show any signs of accreting matter.
Current theory indicates that once matter (or light) crosses the event horizon, it can never leave, since the escape velocity exceeds the speed of light.

Any matter that enters the black hole will be destroyed. Also, it will increase the black hole's size.

noone can go black hole as the name suggest it is a hole which is black so how any one can go ad com back...
We know nothing about the conditions within a black hole, but it seems unlikely that a black hole could exist within a black hole, or even if this concept would have any meaning at all.
no
No, we have not seen any evidence of a black hole in our solar system.
That is very likely. 1) Every larger galaxy, or most of them, have a supermassive black hole in their center. 2) Since a certain percentage of star eventually become a stellar black hole, any galaxy should have several stellar black holes,in addition to the supermassive black hole.
Once anything crosses the black hole's event horizon it will not be able to escape.
There is a black hole close to Earth, yes. It is 1,600 light years away.
All the matter that collapsed into the black hole, as well as any matter that fell into the black hole after the initial collapse. The only distinguishable part of such matter is its mass - any structures of matter, even atoms, get destroyed.
Any matter that gets close enough to a black hole can be absorbed by it. But there are no known black holes nearby - the closest known black hole is at a distance of 3000 light-years.
