say WHAT ? really...geeeeese

PS: the shape of the Earth is irrelevant for a level to work.

Everything is irrelevant to you

The answer is... THERE IS NO LEVEL... it is merely a term relative to the exact point you are measuring at.. What is 'level' at one end of a city is not the same as it is at the other side of that city, even if that difference be minuscule.

It is fortunate for us that the Earth is large enough that we don't see the lean of buildings from one side of a city to the other...

There is no UP either  there is only away and towards the center of gravity.

And yes it DOES matter if the Earth is flat or round, because if the Earth was flat... then LEVEL and UP would exist rather than be a mere concept

No, only irrelevant things are irrelevant.

The answer is... THERE IS NO LEVEL... it is merely a term relative to the exact point you are measuring at.. What is 'level' at one end of a city is not the same as it is at the other side of that city, even if that difference be minuscule.

In your answer, by saying it is only relative to the exact point you are measuring, you are saying that the shape of the Earth is irrelevant too.

And yes it DOES matter if the Earth is flat or round, because if the Earth was flat... then LEVEL and UP would exist rather than be a mere concept

If the Earth was flat and gravity worked as we see it on a round(ish) Earth then a level would work in the same way as it does.

  Well wait just a second there Zorg, you said and I quote "Your task is to explain HOW can a LEVEL TOOL work on a round sphere? This is asking how the tool works not how the definition of level applies.  After all level is a term applied to a perspective that is being observed. This is what the tool does, it gives us in essence, a balance point. This does not change just because the positioning is slightly different some distance away. The tool still does the same thing even at the other end of the city. lol

True  it is all a matter of PERSPECTIVE and relative to the point you are at... so on a round earth ALL these buildings would be "LEVEL"  and all these buildings are pointing "UP"
