You are far from speechless. Not a difference of opinion, difference of perception. A globe earth is impossible. You don't agree and that is fine, because most people have been tricked into thinking that a globe is a "fact".
Some people think flat earth is a "fact", it also is not.
You are like person with one eye. You see enough, but not everything. Eating and the size and shape of the earth are not comparable. So, yes you are deceived, like most people who eat.
I may come across as delusional. but you actually are delusional.
You could not understand half of what I could tell you, so I won't bother.
The truth is a mystery to most people. That is why "scientists" are always trying to discover the truth, because it is rare and valuable. But you wouldn't know that and that is OK.
