Ergo cogito sum

The more I think about it the more I come to the conclusion that Descartes has it wrong. It is not cogito ergo sum (I think therefore I am) but ergo cogito sum (I am therefore I think). 

It is the sensing then perceiving that makes the world. Without this contact between the object world and the mind objects nothing would derive any meaning from an inanimate world. 

All that I am is this perception of my relationship to the world.
