Kurt Friedrich Gödel was an Austrian, and later American, logician, mathematician, and philosopher. Considered, along with Aristotle and Frege, to be one of the most significant logicians in human history, Gödel made an immense impact upon scientific and philosophical thinking in the 20th century.
Gödel published his two incompleteness theorems in 1931 when he was 25 years old, one year after finishing his doctorate at the University of Vienna. The first incompleteness theorem states that
He also showed that neither the axiom of choice nor the continuum hypothesis can be disproved from the accepted axioms of set theory, assuming these axioms are consistent. The former result opened the door for mathematicians to assume the axiom of choice in their proofs. He also made important contributions to proof theory by clarifying the connections between classical logic, intuitionistic logic, and modal logic.
When Gödel died in 1978, he left behind a tantalizing theory based on principles of modal logic, a type of formal logic that, narrowly defined, involves the use of the expressions “necessarily” and “possibly,” according to Stanford University. So the theorem says that God, or a supreme being, is that for which no greater can be conceived. God exists in the understanding. If God exists in the understanding, we could imagine Him to be greater by existing in reality. Therefore, God must exist.

for any self-consistent recursive axiomatic system powerful enough to describe the arithmetic of the natural numbers (for example Peano arithmetic), there are true propositions about the naturals that cannot be proved from the axioms.To prove this theorem, Gödel developed a technique now known as Gödel numbering, which codes formal expressions as natural numbers.
