It's really very simple. Our senses tell us the Earth is flat and our first and most reliable method of understanding the world around us is our senses. I think in any situation the burden of proof should be on the one presenting the theory that is not immediately obvious rather than the one that is immediately obvious.
To use an example that has nothing to do with the shape of the Earth, what if we are presented with what appears to be a living mouse whose activity reasonably duplicates those of an actual mouse? Is the burden of proof not on the one claiming that it is a mechanical construct rather than a living thing? Of course, that person might then open up the mouse and show us the mechanical innards that prove it is not an actual living thing. Then the burden of proof is satisfied, but only after sufficient evidence is provided to show that our senses are deceiving us.
Yes, I agree "It's really very simple", but I do not agree that "Our senses tell us the Earth is flat".
A "dyed in the wool" flat earther asked "It is
baffling at times to understand just how REers can go on and on expressing their beliefs
without opening their eyes and seeing what is past their text books and out the door of their lab".
Well, I do keep my eyes open and what do I see?
- The Earth looks flat - it does!
- 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.
- The sun appears to rise from behind the horizon and appears to set behind the horizon.
- The sun stays the same size as it arcs up and over the sky - it sometimes seems a bit bigger at sunrise and sunset.
- The sun always appears to be a disk, though sometimes a bit distorted at sunrise and sunset.
- Likewise the moon appears to rise from behind the horizon and appears to set behind the horizon.
- The moon stays the same size as it arcs up and over the sky - it sometimes seems a bit bigger at moonrise and moonset.
- The moon always appears to show the same face wherever it is in the sky. (And from wherever we observe it - I have have travelled and seen this).
- The full moon always appears to be a circle, though sometimes a bit distorted at moonrise and moonset.
Note that none of this is direct evidence of a rotating earth, but
I believe is strong evidence of a Globe with a distant (far further than the earths size) sun and moon. So many of these points are "explained away" by TFES using "perspective", "bendy light" (massive refraction), extreme "magnification" by the atmosphere or simply ignored. These explanations are simply quoted with no justification at all!
I could go on about the direction of sunrise and sunset etc.
Of these, number (1) might indicate a flat earth, but then when we try to work out what the sun and moon are doing, we get into big trouble.
The Flat Earth movement just
takes (1) and says "The earth is flat", then gets into terrible trouble
explaining away all of the others with
fanciful ideas of perspective, bending light, "celestial gears", universal acceleration (powered by "dark energy") and on and on.
But all the other points are far
more simply explained on a Globe Earth, though not necessarily rotating. The Heliocentric Globe model came from much more detailed study of the motions of the planets, most of it without the help of any "optical" instruments.
Mind a bit of logic would show that it would be strange to have all of the sun, moon, planets and stars moving (not simply rotating, but with very complex motions) about a comparitively small earth - and that is before we bring Einstein into it!
There are more points you can see around every day (like the movement of the stars at night!) that are hard to explain on any flat earth model without resorting to nothing more than guesswork about
strange things like celestial gears and aetheric whirlpools etc.
The Flat Earth Movement is challenging theories based on observations made over a couple of thousand years and confirmed by many more pieces of evidence collected since the time the Heliocentric Globe Earth was accepted.
So the onus of proof is most certainly on the Flat Earth Movement to prove their dissenting views.
