What do you believe is the single most compelling piece of evidence to help prove the earth is a globe?
For the purposes of this discussion, the fact that you are incapable of learning anything
is proof positive the earth is not "flat."
Let's see now, about your manifest errors:
The horizon does not always appear "flat" 360 degrees around the viewer regardless of elevation, even while flat-earthers say it does.
The horizon does not always "rise" to the level of the observer, even while flat-earthers say it does.
The natural physics of water is not to seek its own level, even while flat-earthers say it is.
Any more false statements you can dream up, Truth is Transitory?
