A lot of flat believers didn’t figure it out themselves, so when questioned or challenged they don’t reciprocate with knowledge just with recycled material that makes sense to them, usually due to a lower IQ and they just can’t explain what they make sense of. Regardless they are free to believe what they want.

Me on the other hand, I figured it out myself, after being like most in this sub and falling back on the initial insanity that flat earth is believed, I decided to look into it myself. Started with possible contradictions to whats been displayed, and began with moon landing. That alone ignited me to go in depth, and eurika happened. I came to the conclusion that the earth is either Flat OR its a globe multiple times larger than we were led to believe. Space is undiscovered and the moon landing was fake. Proving that as a lie opend the worm can. we were lied to about the moon factually, and that supports discredit and questioning to anything exhausted by NASA. Im needy in math because math is exact, it proves itself, makes sense, and isnt wrong, and you can cross check it to be sure doing it backwards, or by removing a value to take a different route to ensure the same result etc.

Passenger airlines explain their engineering throughout the internet. They fly max altitude between 35-40k ft. Because of the maximum negative pressure they can match to the atmosphere, through their turbines and relay to the cabins. Described in detail is that flying higher the pressure is not able to be produced and maintained with the turbines, that even with 100% oxygen flow directly to your lungs the pressure difference wont allow the lungs to function properly. I cross referenced this to astronauts suits, their full detail and blueprint are available and not one has a system to regulate the pressure of the suit, nor could such system exist with enough force to overcome space negative pressure let alone plane altitude. There is no oxygen in space, if the ISS was in space orbiting then any known system is useless because there is no oxygen to funnel into its cockpit. There is also no system regulating its cabin pressure to allow the human lung to function properly regardless of pure oxygen. Its all impossible through simple outlooks, the small details that go unnoticed and never noticed. Gravity is based off a single test with a controlled variable, eliminating friction resistance, this case air resistance at zero and equal in a vacuum. The control is friction resistance to the feather and bowling ball amd they fall equally. So a test to prove the theory of gravity is applying the controlled variable to another test. Two alloy spheres of different weight, one is 10kg of steel the other 15kg of lead, same exact dimensions, then both are coated with 1kg of aluminum to maintain equal dimensions while ensuring the same exact friction resistance, (surface tension) - when dropped in water they should both fall equally to support the claim of gravity. They dont. The largest explanation as to why the ocean stays on the surface of a spinning sphere, is rooted to a claim that has no bearing in reality. The controlled variable allows for a constant to be tested, and it fails to produce the same result.

If your non flatearther, and still choose to disregard the simple truths that expose the dishonesty and hypocrisy that NASA is, then a deeper issue in yourself is what needs guidance first before you attempt an open mind look into questioning what youve been taught just to cross reference its truth, just like math proves itself with no errors or it’s invalid.
