I don't entirely trust in either Mohammed or NASA. Mohammed was a prophet, a human, and NASA is a bunch of scientists, also humans. No human has lived a full life without lying, intentionally or unintentionally. Therefore, I don't put blind trust in either.

since the original request was for aesthetics suggestions, how about sprinkling in famous landmarks for each region

For example:
Great Pyramids of Egypt (near Cairo, Egypt in Africa)
Great Wall of China (stretching across northern china, Asia)
Statue of Liberty (NYC, USA, North America)
Eiffel Tower (Paris, France, Europe)
Big Ben Clock Tower (London, UK, Europe)
Christ the Redeemer Statue (Rio De Janerio, Brazil, South America)
Machu Picchu (Cusco, Peru, South America)
Roman Coliseum (Rome, Italy, Europe)
Taj Mahal (Agra, India, Southeast Asia)


If I misunderstood the original post's request (and it really is meant to just proofread the map), please forgive my misinterpretation
