Hello, philosopher here. During my lectures we debated the existence of God. I know, the topic is classic but here me out. One person said - commenting on the theleological argument - it is possible that God exists but it is also possible that it does not.

Suddenly something stroke me. Listen to thought that was born in my mind: If it is possible that God does not exist then the God is not the God and therefore it cannot exist. Why? Because we define God as neccessary being. And if neccessary being is not neccessary that it cannot exist, right?

So look at this (1) Assume that my shirt is red (2) Assume that it is false that if my shirt is red then God exists (3) It follows: My shirt can be red and God could not exist (4) Then: God could not exist But if God could not exist, then God would not be God so it is contradiction.

So, if anything fails to prove that God exists, then God cannot exist?

Is it valid or not? What do you think?

Have a great day everybody.
