No human free will

If you are the result of millions of years of chance random chemical processes and natural selection, then your brain is nothing more than the sum product of trillions of electrical signals.  This means that you have no human free will at all.  You are forced to do what you do, think what you think, believe what you believe, and act as you act.  You are forced to because of your environment and evolutionary instinct.  Is this reasonable?

Evolutionists often pride themselves in being free thinkers.  But evolution does not allow for free thinking.  If evolution is true, they are forced to think the way they do–by their environment, random chance, and natural selection. ¹  This is an unreasonable position which contradicts our common sense.  On the contrary, the fact that we do have human free will demonstrates that our brain is much more than the sum product of electrical signals.  It proves that we have a soul, something which goes beyond the physical.
