ausGoeff are you the only logical guy on this forum or are there others like you? because I don't know who is normal (round-earthers) and the others ?
Nope. There's a lot of other logical guys on this forum. (But I thank you for the indirect compliment

) You'll find out in short time which members follow the path of logic and empirical, or evidence-based science. And most will be round earthers. Which is not to say by any means that
all flat earthers lack the powers of logic and reason; many do, and mount a lot of in-depth arguments that require a sometimes lengthy degree of investigation and rationale on the part of the round earthers in order to formulate a response.
One of the main reasons I frequent this forum is that it makes me think and consider
my beliefs about our planet and the cosmos and space travel etc.
The other thing to bear in mind is that it's entirely possible (but infinitely improbable) that the earth
is flat, and that the population has been lied to and deceived by persons unknown and for reasons as yet unknown for millennia. There's a thousand questions that science doesn't yet have an answer for, but there's also the fact that neither do the flat earthers.
As far as I'm concerned Occam's Razor more than adequately supports my acceptance of the earth being an
oblate spheroid.
(Stephen Hawking writes in A Brief History of Time: "
We could still imagine that there is a set of laws that determines events completely for some supernatural being, who could observe the present state of the universe without disturbing it. However, such models of the universe are not of much interest to us mortals. It seems better to employ the principle known as Occam's razor and cut out all the features of the theory that cannot be observed.")
The last bit is the telling bit. We need to dismiss as unproved anything in our theories of the planet that can't be physically observed and/or replicated. Nearly every one of the known spherical earth's data and phenomena can be observed and/or replicated, whereas virtually none of the flat earth's proposed model can.
Note too that there is
no such thing as a flat earth "theory". At best the flat earth notion could be described as a "hypothesis", but even that term's being generous in this case; it's likely nothing more or less than conjecture at this point in time.
