1) You are relying on NASA and CGI in text books.
2) I have refrained from insults and I expect the same in return
3) There is no experiment that supports gravity "bending" bodies of water. The only "bending" you observe is from text books, CGI and cartoon images on Google.
1) No, placing two sticks in the ground a known distance apart and using basic trigonometry does not require me to believe anything NASA tells me. No CGI, no photoshop, no fisheye lenses. So does looking at the night sky and noting that I can't see Polaris. It's still unclear why they would want me to believe this, but w/e.
2) Quit being stupid and I'll quit calling you stupid.
3) That is literally how gravity works. Bodies of water follow the curve of the Earth because that is the configuration with the least gravitational potential energy. This is why you see the mast of a ship over the horizon before anything else. Since gravity points toward the center of the Earth, we don't need to worry about the water falling in to space for the same reason people can live on Australia. This is middle school science.
The Sun is a sphere too. Same principles apply there: Gravity pulls the gases that make it up toward a common center. This leads to a sphere(more or less). Do you also believe the sun is flat? What about all the moons of planets with liquid on their surface? What about Jupiter or Saturn? Are they all flat too?
