Intelligent design is nothing but a veiled attempt to argue that we were created by an omnipotent being. So lets see how intelligent our design really is. A human being has many bad design components. The human eye was designed to last about 50 years. The eye is filled with a gel sac that shrinks quite a bit by age 50. This shrinkage sometimes results in torn retina's that, until recent times, caused blindness. Not a big deal because the average life span then was about 50 years so it went pretty much unnoticed. If an omipotent designer had designed the eye you would think it would take into account the fact that we would eventually have a much longer lifespan than 50 years. Especially if he was the Christian God who designed earlier humans to live hundreds of years like Moses and his buddies. What about designing us with skin full of holes (pores) that are perfectly designed to harbor bacteria and cause many people much grief? Then there are inadequate muscles and tendons that tear and break easily. The biggest design element of the human being that makes intelligent design unlikely is the fact that our brain is split into 2 halves and requires a nerve bridge between them to act somewhat in unison. While this may be a good design, it isn't the way an omnipotent designer would make the vessel of a soul. If you want a container to hold something that must not be divided, you don't design it with 2 compartments. 2 compartments can and will be split. The nerve bridge between the halves of the human brain has been cut in operations and these people in effect have two separate consciousnesses. You might argue that the soul is still in one body but it is inevitable that someone will take half a brain from someone and transplant it in another body. If this isn't splitting the soul, if it exists, then you will have to invoke some crazy logic like quantum entanglement to explain the soul not being split too. That would be stretching logic quite a bit. Taking all this into account shows that the intelligent designer wasn't too intelligent, much less omnipotent. All of the above can easily be explained by evolution and natural selection though. I think another bit of evidence against intelligent design is the fact that the universe works by the laws of logic. That's right, logic implies a natural universe, not a created one. Why would an omnipotent being create a logical universe, just because he could? It would be better for his purposes to create a universe of magic and chaos where there were no logical physical laws. There would be no need for an infinite universe. The stars only need to be lights in the heaven. Another words, the universe only needs to be what people thought it was when religions were created. The logic of the universe has only become apparent in recent history, long after religion was invented.
