Q. When I look out my window I see a plane. Therefore, the Earth is flat. How can it be round?
Because you're not high enough.
You see, the earth is approximately 25,000 miles in circumference and 8000 miles in diameter. When you look out your window, you see a field only a miniscule portion of the earth which could be flat, or curved, or U shaped if you were standing in a canyon. If you were standing on a beach and looked out across the ocean, you would only be able to see about 20 miles out into the water until the earth would curve enough for the water to disappear from your visual standpoint. This is exactly why folks thought the earth was flat several hundred years ago. An outbound boat would disappear under the visual standpoint of the observer, therefore it was thought the boat would fall of the edge. It was only when the boat returned did they find out from the captain that they were nowhere near the edge and a few brave souls trevelled further until one day Earnest Balboa (not Christopher Columbus) discovered America.
The most conclusive proof the earth is round comes from the fact that we have countless photographs of a round earth, and so far nobody has ever located the "edge". Steve Fausett departed Salina Municipal Airport (SLN) travelling Eastbound and remained on an Eastbound course until he eventually ended up back at SLN.
For someone to totally ignore the undisputable evidence we have of a round earth in favor of a theory that has a total lack of evidence is beyond me. I have never gotten an anser from any FE'er that gives an opinion of why they believe the earth is flat. Not one. However, I believe the main reason folks thought the earth was flat originated from a gross misinterpretation from a single Bible scripture that spoke of four angels standing at the four corners of the earth.
Rev 7:1 And after these things I saw four angels standing on the four corners of the earth, holding the four winds of the earth, that the wind should not blow on the earth, nor on the sea, nor on any tree.
Here are a couple cross references:
(Zec 6:5) And the angel answered me, These are the four winds or spirits of the heavens, which go forth from presenting themselves before the Lord of all the earth.
(Mat 24:31) And He will send out His angels with a loud trumpet call, and they will gather His elect (His chosen ones) from the four winds, [even] from one end of the universe to the other.
Strong's Greek and Hebrew dictionaries define a corner as a quarter. The four quarters of the earth, and not corner as used in today's language.
This literally means North, South, East and West.
