It's all about faith. Faith in your belief or faith in your science. I actually don't believe that those two are mutually exclusive.
I think the discussion has to be had about Intelligent Design vs. Evolution before you delve deeper into the possibilities.of the different kinds of Intelligent Designs.
People take for granted something like Mount Rushmore as obviously intelligently designed, and might actually mock you if you suggested it was a natural formation. But yet it seems the thought of the human race being intelligently designed gets you mocked, even though we are the most complex organism that we know of, millions of times more complex than Mount Rushmore.
Or, think of this, take a plastic airplane model, toss an unopened tube of model glue in the box, no matter the natural forces applied to the box, how long so you suppose it would take for it to come out fully assembled?
I think it's terribly naive of us to not even consider intelligent design, because to me, it seems the more logical explanation than just popping into existence and evolving into the most complex machines we all are.
