earth

In the last few years there have been very flat earth theories up to now, is it true that the earth is flat or round, the more days the more trusting the earth is flat-shaped, including myself. Flat Earth theory is more plausible than a rounded earth theory that has been implanted in textbooks in school. Many irregularities in the theory of the earth round, one of which sea water, why sea water does not spill when the earth is spinning. Now I also believe in flat earth theory, so we must unite to prove that the earth we inhabit so far is the center of the natural semestas in the form of flat. Do you believe that?
