Teleology: the philosophical attempt to describe things in terms of their apparent purpose, directive principle, or goal.
Science is all about evidence, not philosophy.
I just noticed this: "intelligently designed thing".
Next time be honest. Instead of using code words like "design" to write about your childish fantasies, call it what it really is: "The Magic Man Did It."
A head's up for normal people (not know-nothing bible-thumping science deniers):
The 1st chapter of the book published in 1961 called "The Blood of the Lamb" by Peter de Vries is all about the evidence for evolution from embryology.
It is difficult for me to imagine the stupidity required to throw out two centuries of scientific progress and replace it with the most moronic fantasy ever invented, "Magical Intelligent Design Creation Out Of Nothing".
Update: One more thing. "Imperfect designs are also the products of designers, so a design’s imperfections cannot rule it out as a created thing."
You are comparing something manufactured by humans to something that requires a god fairy's magic wand. Humans don't use magic. Therefore your comparison is ridiculous, not to mention childish and idiotic.
There is no debate about the established truth of evolution which is the strongest fact of science. What you need to do is grow up, educate yourself, and face facts.
