Can atheists trust their own minds?

This guy doesn't understand the driving forces of evolution. Evolution would push a species to perceive the world as accurately as possible in the context of survive (whenever it aids in its survival). Humans belong to the intelligence niche, we survive based upon how accurately we are able to view and understand the physical world around us (knowledge is power). An atheist isn't able to understand exactly what he/she is, but a theist is much further away.
