So you had to remove my link and post a video I never even posted to refute a point I never made? Adhesion mate. Even without mass, scale and gravity, you suggesting surface tension etc, and the adhesive qualities of water we see every day, in raindrops hanging of objects and on windscreens, utterly demolishing your idea that water not only can not cling to anything, but always has to conform to the shape of a flat tray when that is demonstrably not true. That is even discounting the reality of gravity being so important that is not only accounts for the seas being pulled down into an uberdense center and adhering to the surface of the spherical earth but for the actual shape of our global earth.
