6. This is contradictory, and due to this, statement 2 is affirmed.

Wow, this sounds a lot like the Ontological argument, which is centuries old and which is completely ******y and gay.

It's never clear in the argument what "greater" means, and why existing in the mind would make God less great. If God existed only in the mind, then there would be nothing to assign greatness to, since he would not exist. The whole thing is just a semantic mess, and it doesn't take formal logic to point out vagueries in the words being used.
