dude, the point is that I have proof, me. I could care less if you believe in my thought processes. The only person who needs to know that is me.
Of course, if we were going for proof, the only thing i could give you is products of what my ability to think allows. For example, my ability to think allowed me to write a response to your response. You can SEE these words. If you were standing before me, you could hear the words coming out of my mouth. The ability to think allows me to cook, which you could then taste, if i fed you. You would also be able to touch and smell the food as well. Basically, thinking is an action in and of itself.
You cannot use your 5 sense to prove it's existence, but we know that we can think, because we do it all the time. In this instance, the defense of personal experience is all we need. Thinking is a phenomena that almost(i'd say everyone, but gotta allow for the loonies) can do and accept that everyone else can do. Only if you are mentally unsound will you question ANYONE'S ability to think. That wasn't shot at you, simply a statement in general i'm trying to make.
And honestly, if you think that i can't think, then why bother talking to me at all?
But to tie this together to god..... Well, it's pretty simple actually. God is a phenomena that not everyone has experienced, if you will. Thought is, for the most part. So honestly, what it comes to is that i feel that your attack of thought as a defendable ability is foolish, because it does far better in defending it's existence(while doing nothing but being what it is, btw) than god does.
But please, refute my comment, and please make sense. I mean, you think you talk to god, so making sense probably ain't gonna happen, but please try.
