Also, explain why our sky is blue. That definitely pertains to having an atmosphere...notice the word sphere in there.
We know there's an atmosphere...think before you type .The atmosphere doesn't deplete into space thanks in part to interactions with dark energy. Hey here's an idea: read the FAQ
Gravity is what what holds our atmosphere in place. And I already read the FAQ. There is no such thing as "dark energy." There is no giant ice wall...well, actually there is, its called the arctic shelf, but not in the sense that you people believe. None of your sources are credible in my opinion. If the earth was flat, you would have some way to prove it. I on the other hand, have seen the earths curvature for myself, and can say without a doubt in my mind that it is spherical. On top of that, we have satellite images, we have live footage from said satellites of our earth! This goes far beyond graphical capabilities, period. Graphics will never be that realistic and tangible. What is your proof against all of this? This so called world conspiracy is absolute crap! Also, our systems of longitude and latitude based on the world being a sphere. Look at the curvatures. Nothing you say can dispute the fact that, from high altitudes, you can see the curves of the earth on the horizon.
