Yep, it's FLAT! If you DONT think the world is flat then ask yourself 3 simple questions.
1. Why is the sky blue?
2. Why does thunder echo?
3. What makes rainbows?
Don't you find it amazing that you and everyone you know are completely unable to answer any of the three simple questions. Oh yes, you can bull $#!+ a kid but you can't REALLY answer these questions and you never could. WHY?
Quick answers:
1. Sun light (white light) being scattered by the atmosphere.
2. Air particles moving and creating sound waves.
3. See 1.
Those questions are completly irrelevant where we live. We could live in a magical donut and the answers would still be valid and same as above. Those are just basics laws of physics. They could even work in a flat earth computer simulations if it would be written right.
