We aren't entirely certain how to measure the "size" of a black hole, other than by the mass. Is it the singularity itself? Or the event horizon?
Personally, I suspect that there is a lot going on in there that we currently have no clue about, and that if and when we finally understand it, we'll say "How could we have ever been so foolish?"
Mathmatically, the singularity is a point without a size; just mass. A neutron star is far LESS massive than a black hole, but the physical size is far larger; and the density far less than the "infinite" density of the black hole. (This is why I believe that we don't know everything there is to know about black holes, and that much of what we DO know, we don't yet understand. )
Isaac newton's laws of motion work very well UNTIL you get into the realm of the very small, very large, or very fast. Then you need to add in Einsteinian relativity to make things work.
I suspect that there is some other physical principle that will be needed to modify relativity to understand black holes.
No, Black Holes are not located in Earth's thermosphere. Black Holes are massive cosmic entities found in space, whereas the thermosphere is a layer of Earth's atmosphere.
Yes, that's where they are. A black hole on Earth would utterly destroy the Earth, in a very short time.The existence of black holes is now generally accepted, by the way.
Black holes do not form on Earth. Black holes are created when a massive star collapses in on itself, leading to an incredibly dense core where gravity is so strong that not even light can escape. These events typically occur in space, not on Earth.
Black holes are black holes - they are totally different from anything else in the universe. Most black holes are formed from the collapsed cores of dead stars. There are supermassive black holes in most galaxies, but it is no known how they formed.
No, black holes are astronomical objects that form in outer space due to the collapse of massive stars. They are not found in Earth's exosphere, which is the outermost layer of the Earth's atmosphere.
Earth is a planet. Center's of galaxies sometimes contain black holes. Planets can't be black holes.
Black holes does emit radiation, but they cannot be detected from earth. We use gravitational lensing to "see" the black holes.

No - at least no black holes as defined by physics.
No. Earth was formed by the accretion of material in the protoplanetary disk around the newly formed sun. Black holes were not involved.
The Earth has never been endangered or harmed by a black hole, and chances are, never will be.

Black holes could be dangerous to people if people were close to a black hole, but there are no black holes near the planet Earth (as far as we know) and the closest one is probably in the center of the Milky Way galaxy, which is about 80,000 light years from Earth, which is a safe distance.
Black holes emit so very little radiation they are hard to see. Many black holes lie at the center of galaxies and there they are hidden by stars and dust.
No
They don't. They never have. They never will.
