But... this does not make any sense. you guys do realize ALL civilization learnt from each other?
There is no civilization that did not take something from another civilization. Now, I am talking about all the major civilizations that had a great impact on the world such as Persian civilization, Indus valley, chinese, egyptians, Greeks and so on.
This thread is like asking who was the greatest scientist of all time. All scientists learnt from each other, without the people who created the concept of number and additions and multiplication and algebra ( algebra was invented by Persian :p) then would Einstein and newton really would had made their contribution? newton even said " If I have seen further it is by standing on the shoulders of giants" what he is saying is, he might look very smart, but without the people who came before him, he would be nothing.
So love of our countries aside, lets be logical... How would you even start by defining the greatest civilization when all of the civilizations are so interconnected?
You know, questions like this serve no positive purpose but create hare
I love all cultures because they are all beautiful. all of them.
Instead of comparing them, enjoy them.
