This website exposes the flat earth deception and proves that the earth is globe shaped.
Geodesy is the science of accurately measuring and understanding three fundamental properties of the Earth: its geometric shape, its orientation in space, and its gravity field— as well as the changes of these properties with time.
How does your airline pilot know which direction to head when he’s over the ocean with no landmarks? How do we know the exact boundaries between parcels of land and between states and countries?
These are questions we answer with geodesy (sometimes known as Geodetics Engineering): the science of how we characterize the shape and size of the earth.
These surveyors have painstakingly taken measurements from point to point, and using geometry and triangulation, have determined the size of continents, and the shape of the earth.
Geodetic surveying reveals that the angles of the measured triangle exceed 180 degrees, proving that the Earth is curved. This is called ‘spherical excess’.
If the Earth was flat, the angles would add up to 180 degrees.
One of the biggest perspective problems is that flat earthers are applying the 8″ per mile squared earth curvature formula to wrong line.
Let’s apply this to a picture to see the difference between the level line and the horizon line.
Flat earthers are looking out to the vanishing Horizon Line which is about 3 miles out, and using that line to apply the formula, which is wrong. Obviously the perspective is exaggerated by the small globe in the image below, but the point is the same.
The curvature formula applies to the Astronomical horizon, which is the line created by looking straight out. In the above image it points out to the sky.

Flattening the Earth: Two Thousand Years of Map Projections by John P. Snyder.
As long as there have been maps, cartographers have grappled with the impossibility of portraying the globe earth in two dimensions.
To solve this problem mapmakers have created hundreds of map projections, mathematical methods for drawing the round earth on a flat surface.
Yet of the hundreds of existing projections, and the infinite number that are theoretically possible, none is perfectly accurate.

It’s quiet upsetting, I came here desperately hoping to debunk the flat earthers (one who is my mum) using the Sword – Bible, but instead I just see sharp teeth which goes against James 4:11-12.
The more I see of this type of sharp teeth, the more I am beginning to wonder! At least they use the Bible, but no where in which I turn can I spur them with the Word. NONE.
From my observations I see two parties: one party uses a sword, the other uses sharp teeth and appear in packs. I now have to loose from my soul the vulgar that my eyes just read which is the last place I thought to see such language.
Such a shame, onlookers just see Christians causing discord with each other rather than love each other. Such a shame. I now have to face my mum with no Bible proof.
It’s the flat earthers who have sharp teeth and make statements against me. I just present what I believe to be true.
As for your statement that there’s no Bible proof, I provide it on this page: https://flatearthdeception.com/biblical-proofs-of-the-globe-earth/
And I go through the many verses that flat earthers cite in the free PDF book: https://flatearthdeception.com/book-request/
