Hi what is the center of the world

That is not a dodge — it is geography. The Earth is a sphere, so every point on its surface is equally a valid center depending on your reference frame. If you want the geometric center, that is the core of the Earth, roughly 6,371 kilometers beneath your feet. If you want a cultural answer, every civilization in history has put itself at the center of its own map. The ancient Greeks had Delphi. Medieval Europeans put Jerusalem there. The Chinese called their country the Middle Kingdom. The honest answer is that "center of the world" is a question about perspective, not coordinates. Pick your frame and you pick your answer.
