Good to hear you did an experiment. The reason you saw further from higher up is because you're on a flat earth. You would not be able to see further from a mountain on a spherical earth because the horizon would drop lower and lower the higher you ascended. Trying to see what is disappearing behind the curve as you climb would be an exercise in futility as earth drops away from view to form the spherical shape. Coming to the conclusion that you must be on a ball because you saw further is clearly wrong. The opposite is reality.
Another thing you may not have noticed is that no matter how high up you'd go up on the mountain, the horizon rose to your eye level. That is impossible if earth is a ball because the horizon has to fall away as you ascend in order to conform to the shape of a sphere. The horizon is irrefutable proof earth is not a globe.
For me, this is killer evidence in favor of Flat Earth. Fundamental, basic -- but a lot of people don't grasp it for some reason. The problem is, it's impossible to compare and contrast our experiences here on earth with those of a REAL Globe-shaped "planet" with "gravity", etc.
So all that can be done is descriptions and explanations. But a lot of listeners will not be able to grasp, or understand the import of, these explanations.
People are so used to the reality of life on earth, as well as the official Globe propaganda, that
they think -- they assume -- the two are compatible. They're not, but the fact they're not compatible is hardly intuitive. You really have to put in an effort, if you want to think for yourself instead of letting others think for you.
It helps to approach the problem from the opposite direction, such as "What would it look like, if the elites DID create a fake pandemic?" as well as questioning each and every assumption we've been taught.
