Haha, Sorry if it seemed circular :) rule no. 1 in philosophy is to have very linear logic. Let me put it this way, Anything that is observed exists to the observer > Something that exists any cannot come from something non-existent > You know that you exist > You observe the writing on your screen(the writing exists) > The writing is a product of something (that also must exist) > That something (whether it stems from your own mind or is independently existent) exists > Therefore, I (that something mentioned above) exist.
