    is there a way to see 100% of the surface of earth in person?

        I am not sure about the thumb covering the earth from the moon. The moon is about the size of Australia, and only aprx 400000 Km away, draw the ratio up and , and your thumb will have to be very close to your eye in order for one not to see the earth.

            A person has 2 eyes a certain distance apart, meaning that theoretically if a person was far enough away, they could see slightly more than half of earth. This theory would also state that at great enough a distance, even one eye could see more than half of earth, because there is a small distance between different areas of the retina. So, you would not have to move infinitely far away, but it would still be very far. The question is, at a distance far enough away to see more than half of earth's surface, with one eye or both, would the earth still be visible with the naked eye? Also, what would that distance be, and how would it compare to the size of earth?

                                        Does everyone realise that they're actually a walking, talking, thinking lump of the Planet Earth? I ask, because I never really did, but when I DID realise, it was an epiphany. We are just recycled surface atoms & molecules, rearranged by the energy from the Sun. We are the Earth.

                                          I'm not a christian, but jesus said that he could see the whole world when the devil took him to a high(est) place.. the earth is still flat..

                                              sorry to say, but I'm actually a physicist, and was a big fan of astronomy.. until I saw CGI's of earth's "photos", how astronaut grab his fellow astronaut string, how the moon landing was so obviously faked, how the northen star doesn't match any other animations of earth's and sun's rotation and revolution.. now I kinda believe that jesus wasn't metaphorical-ling those words.. well, mine also said in ambiguous way, but they always match science, or should I say, any science, whether faked or real..

                                                VVindovvZ Recovered #1 That is just a story, and #2 the use of metaphorical language is not exactly rare in the Bible. So given that all physical evidence points to the Earth being a sphere, that's probably a better bet.

Plus hours of 16mm Film images from the same period. There are also a few youtubers that have fun matching up the clouds in their area with all the space images from various sources. It's always correct. See for example SpaceX "Starman" launch where there was a "crocodile's head"-shaped cloud over Australia seen from the Tesla's Camera and several other sources at the same time...

I have looked everywhere and even a professor I know told me he didnt think there were any. All of the ones you see on Nasa website and google images have all turned out to be computer generated photos or created by artists using air brush etc... I’m not being a smart ass or anything, just extremely uneasy about the whole thing. I started by debating flat earth people and got even more uneasy when their evidence for reasons why the Earth isn’t exactly what nasa has told us is actually quite convincing. The other was one link that showed a naval ship spotting a ship from a distance of 175 nautical miles which should be absolutely impossible.

It's not exact, and it ignores atmospheric refraction, but it's OK for small distances (up to a few hundred miles). The usual problem is that flat-Earthers don't know how to apply the formula.

The formula you've cited is not Pythagoras not does it calculate line of sight over Earth's curve. You insist on using it because you think it supports your position. It doesn't, it makes it obvious you're a fool.
