"Magnetized to the Earth's surface is a theory that is laughable to me. But do you have proof of this?" LOL. First of all, magnetism and gravity are not the same thing. Second, HUBBEL [sic] or not, we know really very little about what conditions exist on the huge number of planetary objects in space. Heck, we learn new and interesting things about our nearest neighbor, Mars, with every probe we send there. Scientists can hardly conclude that there are no other planets capable of sustaining life and, to my knowledge, no one has seriously suggested so. Third, scientists know relatively little about "the Black Hole", but I doubt any would suggest there is only one of them or that they "know everything about" them. Finally, as for gravity versus "the vacuum of space" (sucking up our atmosphere like a hairball), I'm sure someone here can point you to a website providing a scientific proof of gravity, or perhaps we can find someone here to explain it to you [do we have any middle school science teachers on SI, anyone?], but if you just want a grammar school understanding of it, contemplate the following simple experiments: 1) Jump as high as you can. What made you come back down? 2) Borrow a child's bow and arrow set. After checking your target area to make sure you won't accidentally shoot anyone, fire an arrow into the air at, say, a 30 or 45 degree angle (45 degrees would be half way between horizontal and perpendicular). Does it keep going into the heavens or does it come back down to the ground? 3) Look in your Yellow Pages for someone in your area offering hot air balloon rides. Shell out a few bucks and go for a ride. What makes the balloon rise? How do you get back down to the ground? Learning is fun. Enjoy.
