"lack of proof situation"? Oh you poor fool, there is no such thing! Your mere attempt is proof! The mere attempt to prove your existence is in itself proof of it. If you seek more than that though, then it becomes proof of recognition, meaning proof that others acknowledge your existence. Existence itself is absolute. It is undeniably true. You exist, and the situational constant is so as well. In other words, you have already proven that you do exist.
