Why do we need proofs? Why can't we just take all true statements as axioms ?

That is a stupid game. The statement "Every prime is an even number" is well-formed, hence it is correct.

Gödel proved that a well-formed statement is "wrong" (meaning false) if it has no proof. The OP assumes that all true statements are axioms. We can conclude that a statement is either ill-formed or false if it is not an axiom.

So you suggest that we can have two true statements that contradict each other?

How did he prove that? Is that somehow related to the incompleteness theorem? I don't know what it means. Can you give a simplest possible explanation? Or at least try to.

Completeness only works in toy theories like first order/propositional
