isn't God just amazing

I have alway be fascinated with comparing the human brain and other parts of the body to computer.The human brain is much like a computer in so many ways, your brain is much like a processor and a hard drive all in one, our bodies created By God are so amazing and to compare the functionalities of the of computers and humans is quiet interesting thing to study.For instance , your heart is like a power supply making the body become alive,but instead of electricity,the heart pumps blood thought out the body giving your major organs,joints,brain,etc... life.Our eyes serve in two ways one as a monitor allowing our us to see things, but also a projector that projects images to the brain that in return allows us to identify our objects and our surroundings, our moths are sort of the opposite of a key board but the function they serve can be to speak so that someone or something can input information.this, leaves me to the ears a person with normal hearing has no trouble using his ears,the ears serve as inputs or our second keyboards,because the eyes can serve in that way too as inputers or keyboards.What I know to be true is that God was the ultimeant Computer designer, but unlike computers this is where we are different ,God gave us free will,computer has to have a controller or a programmer to sit and write or input commands to make the computer function . If,God were to sit there and have to input commands or have to sit down and write program to make us function ,we would be merely nothing but puppets, but that free will God gives us ,we can either use to follow his design for our lives ,or not and choose other paths.
