This statement is true

You have your opinion, I have my opinion.

Ok so by your logic, the statement "spiderman exists and this statement is true" is a true statement and spiderman exists because the statement itself is claiming to be true, just like your statement was. I dont think so.

I disagree.

The meow god statement's truth value is indeterminate. It is not true or false objectively. You state that it is false implying that meow god does not exist, but you can never say for certain that something does not exist making that statement-objectively- neither true or false. But lets not ramble too much. there is a clear definition for the word "true" and you did not seem to consider it before taking your stance related to that statement.

"Meow God exists and this whole statement is false." "Do I summon Meow God?"
What do you even mean. why would you summon meow god based on this statement? my analogy was this: just because a statement claims to be true does not mean it is. "spiderman is real" is implying that something exists, it is not proven that spiderman exists therefore this statement cannot be true or false. "this statement is true" implies that the statement holds a truth value about wether the statement itself is true. but true about what? about wether it is true? how do you determine wether a person who says "i am truthful" is actually truthful just based on what he said? that statement holds no truth or lie. it is just an empty grammatically correct sentence, holding no external or inherent meaning.

"spiderman exists and this is true"

So what happens if someone says:

"Meow God exists and this whole statement is false."?

Do I summon Meow God?
