Flight times depend on things like the distance flown and wind direction & speed, not the shape of the earth.
Fine, yet every single flight time nearer the equator is longer than every single flight time further away from it. That seems quite coincidental if the earth were flat.
The sun disappears when it get's too far away to see, just like a ship over the horizon.
Yes exactly. It disappears over the horizon, as the earth spins on its axis away from it. If the earth were a flat stationary disk and the sun were revolving around above it. It would never disappear over the horizon. And if it did, it would become extremely small before it did. Because on a flat earth, the sun is just moving closer and farther, therefore it would appear larger and smaller, and it would appear as a star in the sky at night and then revolve around again and get larger in appearance again. A spherical earth spinning on its axis explains the path and appearance of the sun the way we observe it while a flat disk earth doesn't.
Just because four of five pieces of furniture in a room are chairs doesn't mean the fifth piece is a chair (And various condescending remarks)
Of course the fact that every other heavenly body in the universe being a sphere isn't proof that the earth is a sphere, but it would definitely be logical to assume so.
A lunar eclipse is caused by a shadow object which periodically appears between the sun and moon blocking the sun's light from reaching the moon.
Of course. But if that object isn't the earth, then why couldn't we see this object? If an object were so large that it cast a shadow on the entire moon, how could it be that we couldn't see this object? And if it is the earth, why is the shadow always curved if the earth is flat? I have yet to see a reasonable explanation for either a lunar or solar eclipse based on a flat earth.
Also, why do people seem to think that the earth spinning at a little over 1,000 miles per hour is such a big deal? Why do people think that it would feel so fast?
I know right? Or even infinite acceleration? What's the big deal?
As I said, take a globe and spin it once every 24 hours. That will show you how fast it is. Have you ever watched something take 24 hours to rotate one time? It is extremely slow. The earth is so large that one rotation around its axis in 24 hours would not even be noticed. We wouldn't even know the spinning were occurring except for the fact that we see the sun and stars moving around us.
So yeah, like I said, what's the big deal?
