You round earthers simply don't understand why all of your round earth evidence is wrong. At the heart of the issue is the fact that every single scientific study verifying a round earth was manufactured by a cabal of powerful people that proliferate this lie in order to benefit from it.
Some of the items on the list have been mentioned by folks in this thread before, but I am relisting it for clarity:
1. NASA is an organization that promotes the round earth myth.
2. The US government is, either in on it, or is deluded by the "expert" claims of the agencies it relies on for such information.
3. Other governments around the world are also, either in on it, or are in conspiracy for themselves in order to benefit from the hoax (here is a list of some of the space agencies that continue to reap the rewards from a round earth myth and continue to proliferate the lie: BSA, ACAE, CIDA-E, AEM, ASAL, AP-MCSTA, ARPSAF, APSCO, ALR, AMAKA, NSSA, BIRA, ABAE, AEB, UKS, ABE, SRI-BAS, CSA, CNSA, CCE, CRISP, CSIRO, CCSDS, COSPAR, DRC, DRKI, ESA, GISTDA, DLR, HSO, ISRO, ISARS, INTA, ISA, JAXA, SRI, NZSA, KCST, NADA, LSA, ANGKASA, NASA, NARSS, CNES, CONIDA, CNIE).
4. Although there is still much debate amongst the flat earth luminaries, the general consensus is that the edges of our flat earth are surrounded by an ice wall. The multitude of aviation and maritime organizations out there, are forced to use navigation technologies that the round earth cabal makes for them, so no plane or sea-faring craft has ever been able to make contact or breach the edge of our earth. The technology, these industries have, simply simulates a round earth through a series of navigational tricks.
5. Members of the round earth conspiracy have infiltrated every scientific and technological field, and are working around the clock to obfuscate the flat earth fact by steering their respective fields in a direction that retains the wool over the eyes of the general populace.
6. The overwhelming majority of science that supports a round earth is manufactured to conceal and obfuscate the experimental data in a manner that allows the agents of the round earth cabal to draw fraudulent conclusions in support of the myth.
7. The few percent of scientific research that has not been conducted by agents of the round earth cabal, overwhelmingly supports a flat earth, and if you think otherwise, you're wrong.
In Conclusion:
As you can see, when you consider the seven facts that I have laid out for you above, you are forced to face the immutable truth - the earth is flat! If, for some reason, you are not convinced, please list any scientific research you would like, and I will be happy to tell you whether or not it is simply wrong or, alternatively, how it supports a flat earth, instead.
I hope everybody reading this understands, that even though practically the only way two people can keep a secret is if one of them is dead, the Flat Earth Cabal has existed for hundreds of years and employs countless thousands of co-conspirators within its ranks, while never having to cover up even a single catastrophic event that would shed light on its machinations.
Or, maybe the earth is actually round...
