Technology (computers, the Internet, and thousands of other things) have NOTHING to do with the "globe earth", nor did the idea of the "earth as a globe" lead to ANY technological developments of any kind. NONE of the technology you use on a daily basis presupposes a globe earth. Nor did any technology "flower" from the foundation of a globe shaped earth.
Most world communication is done via undersea cables and other cables. There are also plenty of towers -- very high, and probably with decent power. When you combine power + height + a flat earth, you can get out quite far.
Satellites, insofar as they exist, are kept up with helium and/or in some kind of air currents. There is no footage anywhere (online or otherwise) of any live satellite. Google satellites, and you get 100% CGI, artists representations. Why do you never see these "satellites" in the background of any NASA footage? It's too hard for them to do. They aren't that sophisticated yet with their fakery.
BTW the first satellites came out right after they came out in Science Fiction. There's an interesting history there.
On the other hand, compasses, sextants, lighthouses, military radar, submarines, levels, and countless other instruments require and presuppose a FLAT EARTH.
Submarines don't have a technique where they go out of range and hug the (curved) surface, making them invisible to radar. But if the earth were a globe, why wouldn't they?
Pilots don't lower their nose every minute for X seconds to stop from flying higher and higher into outer space. Why don't they?
Why do we call them air PLANES? Because they fly parallel to a flat earth.
Water does not bend. And no, a water droplet does not count. We're talking about more than 20 drops of water. Water always forms a flat, horizontal surface on top. No one can demonstrate bodies of water curving AT ALL. But there is tons of evidence to the contrary -- that water is always flat.
I could go on for hours. The evidence for the earth being flat is legion. That's why I believe it. Despite the fact I was taught all my life that the earth is a huge spinning ball hurtling through the vacuum of "space". I know more about the teachings of the Globe paradigm than the average person (probably including you, reading this). I have dug into the subject.
