Earth must be flat or you couldn't tie your shoes on R-E.

Gravity on round earth would pull to the center on every single angle all around and why on paper we see water held all around a CGI globe, but those water couldn't flow due to that gravity on such an impossible sphere. The water would remain pulled towards the center thus remaining where they are.

Same for your shoe laces, gravity would render it impossible for you to move your arms or legs, we'd all look like a bunch of stiff-necked people.
