The former founded geometry and established the famous European spatial axiom. The latter involves a wide range and has made extraordinary contributions in many disciplines.

So if you want to be better than anyone else, you must first know what your excellent standard is. Everyone's standards are different. If I were, I think Euclid is greater.

Because Euclid's contribution is purely groundbreaking, he created an example of deducing the whole branch of discipline with axioms. All mathematicians in later generations benefited from this idea.
