He wrote 13 books in Alexandria making theorems for Geometry
Euclid is given the honor of being the Father of Geometry. In his book, 'The Elements', Euclid defines the concept of points, lines and planes and together with postulates and theorems develops the subject known as geometry. This occurred in around 300 BCE.
Euclid
No one invented prime numbers.
Euclid contributed to number theory, which is the study of integers. He worked on prime numbers and divisibility. He proved the infinitude of prime numbers, which had not been proven before.

Euclid was a Greek mathematician, and is called the father of geometry. A prime number is any number that can only be divided by itself and one. There are an infinite number of prime numbers. As a mathematician Euclid was interested the pursuit of knowledge for knowledge's sake and in proving that things could be quantified (how many, how much). In the case of primes the answer of "there are an infinitely large number of primes" was not available to him as the Greeks did not have the concept of "infinite".

The thirteenth book of "Euclid's Elements" is called regular solids. In this final book, Euclid names and describes the properties of the five regular solids and ends it by proving no other regular solids exist.
Euclid (~300 B.C.). Euclid started with 10 facts that were self-evident and required no proof, called "postulates" and "axioms." From those, he developed hundreds of propositions and theorems, which he proved using only the 10 postulates/axioms and previously proven theorems. The collection of this work was written in 13 books called "Euclid's Elements". Its logical, axiomatic approach and use of rigorous mathematical proofs has remained a model for mathematics and science for over 2000 years.
