Yes
Water is always flat
Never observed to curve

I don’t settle at EM for “gravity”.

people hundreds of years ago didn't knew how to build computers

people hundreds of years ago prayed instead of doing surgeries

Yeh nah but stil it's a better attempt than densitt and buoyancy

Moving water curves across the land. (Rivers and streams)

also water is flat? More or less

Vibration? Electric fields?

Water is affected by electromagnetism. It's otherwise perfectly flat

This is a small-scale version of the Earth

More or less, water at rest is flat. Yes.

Computers,Surgery is irrelevant
They knew how liquids work
They were not idiots

With the North Pole at the center

if you take a little piece of the ocean it's indeed flat (unless you really really zoom in)

but if you take the whole earth, then it's not flat

That water body is small and at rest.

Please show measurable curvature on water or water curving

it's just that we're too small

we need to go to space for you to see it

unfortunetly I don't have such resouces

but spaceX does

The oceans aren’t flat. They have waves.

So in other words
You can’t and only making assumptions

This is how they make glass windows with molten tin ... At 3:30 it says (("the surface of any liquid is flawlessly flat"!!!)) https://youtu.be/IjNusHQOhTM  ..  Flat liquid equals Flat Earth  .. take 10 seconds to watch that video segments

Got it 👍

I can't measure the curvature by that, but I had made other experiments

This stone is curved, curved stone = curved earth

Liquid at rest, yes. All else is broken surface tension.

I don’t care another other experiments
I want to see curvy water

Google surface elevation for Lake Michigan and Lake Huron. They are both 577 feet above sea LEVEL????

you can't, we're too small

and we don't have the money to do so

No curvy water

No curvature found

They can’t show you curving seas, unless they use a wide angle lens or space images.

Rip 8 inches per miles squared

u have to be taller to view a curved ocean

^

like much much more taller
