No human has ever seen the wind, yet we know for a fact it exists. We see its effects.
You don't need to fly into space to know the Earth is round, there are tons and tons of ways to determine this without simply stepping back and
looking at it.
Ever witness the sun never setting far north? That means you are either on top of a spinning sphere, or if the Earth is flat, in the middle of a
spinning disk. If you were in the middle of a spinning disk, then locations far away from that location on either side would be double the distance
from each other, and it would be impossible to move between those locations quickly. But since the Earth is round, you can quickly move between those
two points by stepping a few steps.
I drew a picture to illustrate this point, if you are at location "A" in the middle of a spinning disk, the distance between points "B" and "C" will
be great. But they aren't, on a flat disk you would need to travel either straight across the disk, or somehow wander outside the disk in some sort of
aether environment before coming back to the other side, and even longer distance.
Or, since the Earth is round, we can simply take one step from location "B" to location "C" because they connect, because the earth is round.
Another thing to think about, if the Earth truly was flat, every single airline pilot on the face of the earth would have to be involved in the
coverup. Not because he'd see a flat Earth, but because travel distances would be far far different than what they currently are (because of the
reason illustrated with the MSPaint funny face looking picture) and the pilot would easily know this. Most passengers if they put the effort in would
also easily be able to tell the earth is a globe. You can't fly west from Europe to America, then west again to Asia, then from Asia west to Europe
without the Earth being round. Unless you are going around the edge of a disk, but in that case, you wouldn't be able to go south and turn up at the
north pole again, which you do.
