"god exists" <Why is this a relevant argument?

[Tiberius]

I did not contradict myself, I illustrated the contradiction of the statement "god exists".
Are you able to reply in a way that shows you understand my perspective so I know you're not arguing for the fun of it?

There is no contradiction in the statement "god exists", only a contradiction in your argument that there is a contradiction (and therefore revealing your argument as wrong).

Everything exists is a given by default otherwise we wouldn't be able to talk about it (even if an idea).

Say hello to the Loch Ness Monster the next time you see her.

FYI, ideas about things exist. The things that ideas concern don't have to. You are conflating the issue by suggesting that because we have an idea about something, it means it exists. This is wrong, and a formation of the Ontological argument (where people define things into existence). It has been shown to be wrong many times, as people can use it to define whatever they like into existence.

The proposition argues that "god exists" in reality, not an idea.
=>nonexistence = nothing
given the context of nonexistence as opposed to existence which is the argument about "god".
given that: nothing is an impossibility due to being a paradox (in the same context just mentioned), we have: existence = everything.
So the assertion of in the first "god., must also entail (exists).
=>"god (exists) exists"
double positives cancel each other out so it is a nonstatement or does it equate to: "god does not exist"?

Double positives do not cancel each other out. It is very simple:

God does (not) (not) exist => God does exist.
God (does) (does) exist => God does exist.

In mathematical terms:

-- = +
++ = +

Your phrase "God (exists) exists" simply becomes "God exists".
