euclid wanted to prove that things were true by using logic and reason.

Euclid did not discover math. Math is and was an ongoing process of discovery of the relationship between all things that can be expressed with math formulas. Most of what the ancient Greeks did was based on geometry. Euclid gathered all the geometric information together and tried to systematize it so that it would be easier to understand and easier to learn and/or use. He did nothing with the other branches of math.

Oh honey, where do I even start? We've got the OG Pythagoras, the genius Archimedes, the badass Ada Lovelace, and of course, the one and only Isaac Newton. These math wizards were slinging equations and theorems way before it was cool. So, bow down to these brainiacs who paved the way for all the math nerds out there.
Many ideas of mathematics began to form. During this time frame people began to see math as important and so many thinkers spent time trying to solve the worlds problems using math.

Leonhard Euler made many contributions to math but the one thing he is most famous for is changing the base of the natural logarithim by using the letter e which is aka Euler's number
