What and how do I know?

To know is to have a knower and things to know. Therefore, it entails space, objects, time and consciousness. Existence of things does not infer that there is a god or creator, only the state of affairs is such. For sense-tools to come into existence must mean the knower’s object-self is a priori, and has an “understanding”, that is, assumes the existence of space/object-time.
