The conspiracy itself is proof that the the Earth is a sphere.
So it was concluded several hundred of years ago that the Earth was round. If it were actually flat and that was all a ruse that means over thousands of years this has been kept a secret by all the governments of the world.
Every field of science would have to be in on the ruse. Geology, Physics, Astronomy, etc... Several other fields like pilots, ship captains would all have to be in on it. Not just military ships either but every Carnival cruise captain. Every person that gets a pilots license.
Then every person that becomes a scientist would have to be indoctrinated. But at what point are they brought in on the ruse. 1st year of school, After they get a doctorates. Where is the separation point from those that know and are in vs those that are approaching and realizing the truth but they just aren't saying anything. Why wouldn't some student by now have started to be like hey wait this doesn't make sense and said something? They would be famous and probably become a millionaire.
Every person that works with the scientist aren't saying anything. None of them have told their wife or family about it. It's been kept airtight for thousands of years with not one person speaking.
Bill Clinton couldn't get a blow job without everyone knowing and ratting him out, but a conspiracy this big involving this many people is kept secret.
All these scientist are being paid all this money for fields of science that don't even really exist. What's to gain financially? Some argue it is to hide God but there are tons of religion so if that's the case it didn't work.
Think about all the people, the unimaginable amount of money paid to keep the lid on and nothing is gained. They do all of this and a few random people on Youtube blow the lid off. Wouldn't they just off those people?
I mean look a big oil. Anybody who dares to make a car that runs off water or anything like that is no longer with us! Yeah we have electric care but ultimately fossil fuels are used in large part to generate that electricity so big oil still wins. GO outside of that and you disappear.
That's just big oil. A entity that has kept a secret for thousands of years amongst millions of people doesn't just kill off some Youtube idiots. GTFOH
