G'day Cactus.
I call bullshit on that statement.
You are stating a logical fallacy that because 'A' is true then 'B' is true, when 'A' and 'B' are two different topics (Flat Earth vs Vaccinations).
When you look at the sky, do you see a round Sun as I do?
When you look at the sky at night, do you see a round Moon as I do?
Now, the first image shows two 3:4:5 triangles and a relationship of 3:11 between the Moon and the Earth.
3 + 4 + 5 = 12
3 x 4 x 5 = 60
12 x 60 = 720
There are 720 degrees in the internal angles of a Tetrahedron, one of the 5 Platonic Solids. The Number 720 is also the third Octave of the F# Note (180 - 360 - 720) in 432Hz Musical Tuning, which has 14 Notes (Moon 3 + Earth 11 = 14).
720 x 3 = 2,160 ..... which in miles is the diameter of the Moon.
720 x 11 = 7,920 ..... which in miles is the diameter of the Earth.
Of course, 432 is the square root of 186,624, which is the classical number for the Speed of Light in miles per second.
So, there are direct correlations between the Earth and Moon that 'fit' together with the 14 Notes of 432Hz Musical Tuning, the Speed of Light and the 5 Platonic Solids (the 'building blocks' of all physical matter and the basis for the whole periodic table of elements).
Can the 'Flat Earth' theory provide any direct correlations as presented above?
Further to this, the first 12 Numbers of the Fibonacci series (Divine Proportion) added together ...
1 + 1 + 2 + 3 + 5 + 8 + 13 + 21 + 34 + 55 + 89 + 144 = 376
... total 376 and ...
3 + 7 + 6 = 16
... and ...
376 / 16 = 23.5
... which in degrees happens to be the tilt of the Earths axis and produces the seasons and Precession of the Equinox. Of course the Divine Proportion is inherent within all physical matter through the spiral of the DNA strand, among other aspects.
Can 'Flat Earth' theory provide any correlations with the Divine Proportion (Phi - 1.618)?
After all, a spherical Earth directly correlates with observable physical phenomenon.
