You claimed that the link I provided did not provide a method to measure the curvature of the Earth

It's not really a claim, but what i said was that the link you provided was not an example of directly measuring the surface of water and measuring it to curve convexly the way the globe model describes. There is no measurement of any curvature OR the surface of water in the link you provided, This isn't so much "a claim" as it is plainly obvious and without any possible refutation.

Let me make it very simple

Agreed! This is what i mean by "taking more bites before you are done chewing the one in your mouth". We are still only discussing one claim - my first one. We can get to the rest once we are done with it.

You responded to that claim that there was a procedure to measure the curvature of the surface of water (specifically the curvature described by the globe model) and then provided a link to a procedure which didn't in any way do that. Pretty simple right?

If there is a method to measure the curvature of the earth, it also measures the curvature of the oceans covering the earth.

This seems a bit like a tautology. The oceans are a part of that earth, so if you had a method to measure all of the earth - you would necessarily have to measure the oceans in order to do it... We are currently struggling to measure (even purely in imagination/hypothetically!) even a small to moderately sized lake (frozen or otherwise) - so measuring the entirety of the world instead is obviously quite out of the question.

Do you understand what I am saying?

Yes! And i pose the same question to you - forever and always while discussing. Please ask me questions if you do not understand, or disagree! The more specific the question, the more likely i can provide the specific answer you are looking for (assuming i have it to give, of course!)
