Well, this is where, by simple deduction, most people would beg to differ. In every case where we are able to observe an artifact we assume it is the result of intelligence acting upon the substances necessary to form the artifact. We don't even have to see a hammer in action to understand that it is an object of intelligent design.
As we've been able to form tools of our own to look deeper into the substance of things, we not only find something more complex than a hammer, but we see that it is dynamic, and that is is carrying out functions that have a purpose and yet are completely outside of our control.
I would be surprised and alarmed if I ever saw a hammer pick itself up and start doing its designed task without seeing a human hold it. Yet we see many functions carrying on about us without the aid of our consciousness or observation.
Can you understand why it would be easy to deduce that some kind of intelligence underlies the existence and dynamism in our universe?
So give a specific example, and tell us why we shouldn't study it to see if it can be attributed to ongoing processes.
