the horizen is always at eye level
Go in an airplane and see for yourself that it's not.
the rectilinator experiment shows a reverse curvature
Flawed experiments produce flawed results.
the nazi believed it was and they were more advanced then any nation at the time
The most advanced nations of of any other time in the last 2,000 years believed/believe that Earth is round. The nazis also believed that everyone without blond hair and blue eyes was inferior and that they should be killed so the "Arian race" could dominate.
the movement of stars and the moon prove the concave earth
Look again. Round Earth predicts exact spot what we see down to the exact time of every solar eclipse that will happen in the next few thousand years. There are also things like lunar eclipses which make no sense on a concave Earth. What we see makes no sense at all on a concave Earth unless light bends in nonsensical ways while on a round Earth we simply see what's there plain and simple no illusions required.
the refraction of light proves light bends around the earth
You don't know how refraction works do you... Refraction would only support concave Earth if the atmosphere got rapidly denser as you got further up, but if you have been at the top of any mountains lately you would know that in reality it's the exact opposite. The air would eventually have to get so dense that it would be opaque and we wouldn't be able to see the Sun. Since the atmosphere gets thinner as you get higher up that means that refraction causes light to bend down and make things appear higher in the sky then they really are, and yet we can see stars on the horizon.
Earth is round, deal with it. The real Christ didn't say anything about the shape of the Earth, so why do you think that he would inconspicuously come again and completely change his ways to include making animations and threatening to murder the president?
