I apologize for the tone of my previous messages. Octavia, you just assume you are on a globe and you just assume some celestial bodies are globes because you are on a globe. Think about it. If you're interested in the matter, I invite you to watch "ODD 21 questions" on youtube.
So... if you see a ball in the air, you assume the basketball court is ball-shaped? This is the best argument ever! You really are a genius and I'd be really honoured to debate with you, and I'm lookin forward to seein your proof that celestial bodies are all spheres.
