I also have some questions

1)the earths curvature can be seen from a plane-how?
2)why if the "sun" and "moon" are 2 huge lights circling 3000 miles apart, do we get eclipses?
3)if these lights rotate once per day, it could plausibly explain day and night, but how do we get seasons if the light source is a fixed distance away every day? and how does somewhere like Norway have constant light for months?
4)what is the circumference of the flat earth?
5)Why, if the flat earth map is accurate would flights from the UK to Australia go via Dubai?, its the wrong way
6)Likewise, going by the map North Africa is wider than the US, so why does it take twice as long to fly from New York to LA?
7)and again, New Zealand is closer to Alaska than it is to South East Asia, So why does it more than double the time to get there?
7)How wide is the Antarctic rim?, and how do you know that, if its guarded and people aren't allowed there?
8)What causes tides? if it was some huge underwater wave machine it would send waves in multiple directions at the same time
9)If there is no curvature why do you see the top of an approaching ship first? it should all become visible at the same time

I doubt i will get any replies but id be interested if anyone can give me a reason how these facts fit in to a flat earth theory
