It's level, not flat. Measuring flat-ness is a whole different complexity and ball game.

You mean a whole different disc game.
Yep, we use laser trackers at work to define flatness. I'm sure that much isn't required, but it's down to .003in, so pretty flat and it's fast. But that's a literal laser instrument designed to do such things and costs 250k. I guess you could with a faro arm or romer arm, but again, those are still 10s of thousands of dollars. CMM? Those can get reeeaaallly pricy
Some ancient Greek nerd calculating the earth's circumference by measuring shadows: Am I a joke to you?
It's flat all across the globe

And level! It must be at the center.
No, you are at the top. If you were at the center you wouldn't need a level to tell you.
Great illustration of the issue underlying flat-earthism. 👍
You actually proved the exact opposite.
That dry, dusty ground proves that water can't always find the level.
Find the level. Yeah, I'll show myself out.
The haversine formula is more accurate than a straight line in measuring distances around the size of cities or zip codes. Geodesics are even more accurate because they take into account the stretching around the equator, both require curved earths to calculate more accurate distances than flat calculations. But obviously math, especially addition, is a conspiracy to cover the truth of the Time Cube™. /s

Can it find my level? I lost it 🥺
If water finds it's level, why is the bubble finding the level? Open your eyes!
I think you'll find that it's a bubble on this case. Big bubble is selling the round earth theory to sell you more bubble levels to find flat locations.
OP found a manifold, and stampeded straight towards the wrong large-scale interpretation.
Like an Earth-measuring version of charly kirk on the gun issue, and look at him now, where that got him.
