Natural Selection Seems Insufficient

You spoke of rewards incentivizing behavior. A free agent has the freedom to dictate his destination, he can shift direction on a dime to pursue the reward/ incentive.

Determinism lacks that freedom and flexibility.

I'm beginning to think your "can't understand" really translates to "I am so convinced of evolution that anything counter to it will not compute in my brain."  So yes, it might be impossible for you to comprehend the argument, at this point. Literally. In that case, I don't think I can help you understand.

Ok so on this part:

You spoke of rewards incentivizing behavior. A free agent has the freedom to dictate his destination, he can shift direction on a dime to pursue the reward/ incentive.

You know that this is literally what happens in your brain? I'm not saying everything that happens MAKES you do something, but the reason why you feel good when an action or task or someting is done, is a literal chemical in your brain making your do that? Its literally a "reward center" - again thats why people can be addicted to eating to much or drinking too much. Its a self high that makes you feel 'good'. 

Its not determinism its "you do something, your brain literally releases a chemical that makes you feel good" - determinism is philosophical in nature. I'm talking about "Evolution is a process that does X" - if anything else is present, as with any science based theory, you are free to prove otherwise. 

All of the above IS something that comes as a product from evolution. I mean my "lack of understanding" comes from you not knowing what your own point is I think.
