Although I discourage pondering such questions when in the throes of DR/DP...
1.) The earth came about, roughly 4 billion years ago, as a consequence of the rubble left over from the creation of the sun. As to 'we' got here, well, the idea is that amino acids in the primordial ocean evolved into simple cells (this has been reproduced in labratory conditions) and from then over evolution took over.
2.) Yes, gravity is holding us to the ground. The earth is not 'floating' in space, it is strictly held to a eliptical path around the sun. We're not going to float off into the void.
3.) Yes, it is pretty startling, but not as amazing as we might be to an ant. But if the sun wasn't exactly where is was, we wouldn't be here today. Too hot or two cold, and the conditions for life wouldn't be there.
4.) No.
