When we admire an impressive work of art or impressive piece of machinery we readily conclude that it was well made by its creator.
Yes because we know that art asn machinery is made by humans. It doesn't reproduce therefore it isn't subject to the actions of natural selection.
Biology is NOTHING like art or machinery.
Yet, when we look at life in all its incredible diverse glory we are encouraged to conclude that it all arose spontaneously because it was supposed to: no creator required
'Glory'?
What about all the stuff that is amazingly 'designed' to kill and devour other stuff? The microbes that do nothing except kill and reproduce for example?
