Why is the world round?

I am generally not a bull-shitter. But this time - absolutely could not help it. Had to write this. Because all my prayers to fall asleep at least before three in the night are never heard almost every single day round the year. So I thought. The rascal in me set the neurons in my silly brain into that stormy rebellious motion. A simple rage. An easy question. Why is the world round? 

But no answer. Well, certain things have no answer is what we have been told. Or so we were made to believe - right from when we were kids. The beginning of each of our times. Would that stop us from thinking the things that we, by societal dictum, are banned from thinking? Nay, a hell capital NO is the word. The right word. So, back to the question. Why is this world round?

This had not stricken me as hard as this. I know what you're thinking. No, you don't have to stress your mind in that wrong judgmental angle. Oh yes, I perfectly understand. Your next question is - Dude, what happened to you and what is wrong with you? I can sniff that dirty trail of your thoughts. But no dear, I don't drink or smoke or do drugs. Girl(s)? No time for that! Oh, guys then? No thanks, I am straight. Sincerely straight. Oh got it. Are you in love? Well, who in this big round world is not? May be there lies the answer. But dear, infesting your thoughts with love - to find an answer to a pressing scientific question - is definitely not the right move. It would only lead to much confusion. Tell me - why is the world round?

Now the converse view. Had the world been flat, would it have created the scenic beauty and the evergreen imagery that we romantically call - nature - for our hearts to joyously revel in? The mountains, the rivers, the dry land, the forests, wild life and the oceans duly reveal that there is no fun in the world being just flat. But why? Is flat the correct opposite of round? - that the connections we make here and the reasons we build - suffice to quench the question that burns my sleep away. Why really is this world round?
