Alright tutoring time😂😂😂water doesn't flow downwards cuz of the gravity in the earth's core same as why u don't keep on rotating earth everytime you jump....reason if the earth is flat there wldve been no end or u wldve found a chasm to space where as it is proved that if u bypass the core and pressure and gravity under earth u can dig down to another country the reason why the sky appears flat is cuz the curve of a telescope and the sky is almost the same so it'll appear plain and flat and the reason why u don't reach the sky is cuz there ain't no sky the blue thing u see is a reflection of oceans even if u are far inland...I suppose I don't have to prove gravity to u since u seem sensible so straight ahead and a scenario of my own...if the earth was flat wld u think there'll be air...or we wld prevent the uv rays coming from the sun? Our ozone wld have to meet up with itself so that alone dictates there is no way that earth can be an infinite plain and the way the sun and moon travel on the sky proves that the earth is a spherical shape because the path isn't straight it's higher at midday from sunrise and sunset this making a curve on the sky and besides easy way to prove it put a stick in the dirt at morning and watch as the sun creates a shadow behind it...if it was a plain it shld only change directions not grow taller and shorter with the sun showing that the earth is once again spherical...thanks for bearing and reading with me😂😂😂
