What I am surprised with is the amount of research done on the subject of a flat Earth and the certainty with which so many believe it to be true.
What I'm surprised by, frankly, is the certainty which YOU have that the earth is a globe. You've spent 90% of your waking hours dedicated to exposing how modern science is a fraud, and yet you believe their claims regarding globe earth? It's incredibly naive coming from someone who's done as much research as you have regarding the fraud of modern science.
BTW, cassini, your use of Coriolis effect is rather astonishing to me. Coriolis assumes that the earth is in motion. Geocentrists hold that the earth is both the center of the universe and STATIONARY (that was one of the arguments for geocentrism during the Galileo era, that Sacred Scripture teaches that the earth is immovable).
So how do YOU explain the "Coriolis effect"?
It's mind-boggling to me that a geocentrist would not be in agreement with the "Flat Earthers" regarding the Coriolis effect. Are you in such cognitivie dissonance that you didn't even recognize the contradicition here? When people are in self-contradiction, that's the clearest sign that they're filtering stuff out.
So do you suddenly believe that the earth rotates, in denial of Sacred Scripture? You do realize, right, that the Coriolis effect is attributed by "science" to the rotation of the earth? I'm, quite frankly, gobsmacked by this thread.
On top of that, you create a straw man. Very few flat earthers are "certain" in the sense of absolute certainty, since we have no smoking gun proof. Some of us are morally certain, but that's as far as we can take it. But the premises of flat earth are persumably principles that you share.
1) Modern Science has perpetrated so much fraud (from evolution to heliocentrism to the age of the earth and how long human beings have been on earth, to the fake moon landings, to the fake ISS footage), demonstrably motivated (from their own writings ... as amply demonstrated by Sungenis with myriad citations) by an ATHEISTIC agenda. Consequently, NOTHING they say can be taken merely on their authority.
2) So if you take the "authority" of modern science out of the picture, and we must, based on the above, you have to start investigating yourself. Flat Earthers are constantly conducting experiments and arrive at findings that are in contradiction with the approved narrative of atheistic science regarding the shape of the earth.
