Yes, very nice videos and articles !!! But i have one last question which i didn't find mentioned in these videos and articles. If the Earth is Flat shouldn't we be able to see all the countries standing on top of Burj Khalifa using powerful telescopes ???

Due to perspective and atmospheric conditions you can only see for a very limited distance even using the strongest telescope. It would blur out long before you could see across to other countries. You can see the perfectly flat horizon from Burj Khalifa and my explanation of the "two sunsets" phenomena starting at 11 minutes here:
