The brain is a machine. The mind is something far different. What is the mind and where did it and intelligence come from if not from other intelligence?
If you are claiming that intelligence is a byproduct of certain natural forces which came together at random, you have nothing on which to base that.
Intelligibility is a property of things which have properties that enable observability and which are logically consistent. All instances of any physical object has properties which allow those objects to interact with other physical objects. That interaction is a sensing process. The universe is intelligible, because all forms of energy that exist in it have properties which determine the nature of interaction(the sense/relationship process) and are logically consistent.

INDEED! INDEED!
The mind results from the funtional abilities of the brain.
