Sure to your eyes the earth looks flat, but when I look around with open eyes I see numerous things that simply do fit with that conclusion.
Everything from the sun and moon staying the same size all the time they are visible to the sun rising in the East (here and I gather EVERYWHERE) at the equinoxes - you might check it out on 7 days time - I see it rises almost in the east here now.
So I what do I see with my own etes:
Lets see about that.
- The Earth looks flat and the horizon looks flat - it does, simply because the earth is huge![1]
This is actually a case of you disbelieving your own eyes.
- On a clear day looking out to sea the sky-horizon interface is a sharp line (it is only about 5 km away!). On a flat earth it would have to fade into the distance with no distinct boundary.
I see things get squished into the distance until they are so small that I can't see it anymore, creating a line. Nothing about that is incompatible with a Flat Earth. The same is seen on computer games.
- The sun appears to rise from behind the horizon and appears to set behind the horizon.
No one sees this. We see the sun intersect with the horizon. No one sees it go "behind" it.
- The sun stays the same size as it arcs up and over the sky - actually it sometimes seems a bit little larger at sunrise and sunset.
If you saw the sun get larger at sunset then that is evidence that the sun is undergoing an enlarging illusion of some sort.
- The sun always appears to be a disk, though sometimes a bit distorted at sunrise and sunset.
The sun is a globe in Flat Earth Theory. I am not sure what you are getting at.
- The sun always rises due east and sets due west on each equinox - here, and I am told it happens all over the earth.
I highly doubt you saw what happened from every point on the earth on equinox.
- Likewise the moon appears to rise from behind the horizon and appears to set behind the horizon.
No one saw this.
- The moon stays the same size as it arcs up and over the sky - it sometimes seems a bit bigger at moonrise and moonset.
Again, admitting to an enlargement illusion.
- The moon always appears to show the same face wherever it is in the sky. (And from wherever we observe it - though we have to travel for this observation).
That's not actually true, the moon does shift a little (although admittedly not as much as it would according to classic perspective on an FE.. but we say that classic perspective theory is wrong, anyway).
In fact, over time, the moon shifts so much that it was possible to make a map of the back side of the moon decades before NASA claimed to have sent space ships to look there.
- The full moon always appears to be a circle, though sometimes a bit distorted at moonrise and moonset.
