If you unironically have fallen for the flat earth CIA psyop, there is one easy experiment you can do to prove yourselves wrong.
Step 1: buy GPS enabled go-pro
Step 2: buy high altitude capable balloon
Combine the two, watch the balloon go up, track where it lands, watch the footage for yourself and free yourself from Mockingbird bondage.
For a little extra, you can configure a live feed system and watch everything in real time all under your control! Yes, it really is that simple!!!
But you are not even comprehending the numbers you are citing. What you are saying is that the land area is nearly a third that of the entire Earth and about half that of the oceans themselves. This is not "tiny."
Where did you get half from?
70% water 30% land
In rough terms, 30% is half of 70%. Land area is about half of the Oceanic area.
Why are you dividing the water in half? You added a step that doesn't belong here lol.
Water (70%) + Land (30%) = 100% (Earth)
Land (30%) / Water (70%) = (about) 1/2
The area of the land is about half that of the water. The land is not "tiny" by any reasonable criterion. But I can now see that comparative mathematics is not your strong suit.
