Another argument from total ignorance: total ignorance of the person you are talking to because you have no way of knowing where I have been or what I have done for work in my life unless I tell you. But since you now say that you have been a roofer you should have no problem understanding parallel lines and perhaps how tack lines for roofing would work on a dome roof or dome shaped house. Your tack lines would be circles around a dome; which is pretty much the same as how they would be on a sphere, for example, the tropics and the equatorial lines on the globe earth, which are not just lines but circles.
In the following video this person takes three measurements: a measurement of a section from each of the tropics and a measurement of a section from the equatorial circle, in the places over Central and South America where these three imaginary lines, (circles), cross over the land. And these are not even precise measurements, but merely close approximations from Google Earth, and yet by the math he proves that the lines are not only parallel circles on a globe but that the measurements come out very close, close enough, to what science says are the mileage circumferences of the equator and the tropics. Not only that but the two tropics are equal in circumference and therefore cannot work the way they are proposed on the flat earth map because they are in no way equal circumference circles on the flat earth map, (which, as has been proven already, is not a flat earth map at all but rather an azimuthal map of the globe earth as viewed from above the north pole).
But taking these three measurements, and measuring the amount of TIME it takes for the sun to cross over these portions of the land masses where these three circles are located, this one simple equation proves multiple things about the earth we live on:
1) The tropics and the equator are parallel circles around a globe.
2) The earth is therefore a globe.
3) The equatorial "great circle", (of a sphere), is greater than the two tropic circles.
4) The two tropic circles are equal in circumference, (which cannot be true on a flat earth).
5) TIME and time zones: the time zones are correct, (but they are drawn by
political lines).
6) ROTATION: the time zones show that the earth is rotating, (about 1000 mph).
7) The earth is therefore a globe rotating on its axis at about 1000 mph.
Just imagine for a moment that you are roofing a globe shaped dome: when it comes to the bulge you would probably draw your tack line at the bulge first, the greatest circle, then you would draw your parallels upwards and down under the bulge knowing that you can hide any excess or lack with a cap at the top and trim work at the bottom. The tack line at the bulge is your equator and the two parallels directly above and below are the tropics. Can you follow the sun around your globe-domed roof so as to shingle it your way as you described above? Only if the sun is circling your globe roof: so either image the sun circling your globe roof or follow your tack lines and make sure the circle at the bulge is level and the rest of your lines are parallels, (lol).
