What do you know about yourself?

If the only thing that you truly know is that you exist, what do you know about your existence?

After contemplation on the only true fact you will realize that there is a tremendous gap between knowledge and assumptions.

After understanding the “I exist” concept some people return to tangible comprehension. People say “I know I exist and I can’t know anything else, shouldn’t I return to my regular senses? Without using my senses nothing seems to work.”
I previously mentioned that even logic is uncertain. We may be programmed to think the way we do.

Let’s face it, at the moment you are stuck in your program. You must therefore trust that 1) if there is a creator he gave you the tools to accomplish what you need. 2) If there is no creator you could only use the tools you have to figure out who you are.

What is the closest assumption to the knowledge that “I exist”? Is there an equal gap from ultimate knowledge to all logical facts such as 1+1=2? Or, is there a logical way to measure the distance between the ultimate knowledge and levels of assumptions?
