Your claim has the same form as someone saying, "a loaf of bread can be made without intelligent design" and then making a loaf of bread and claiming that is the proof of your hypothesis.
But they've only proven that you could make a loaf of bread through the intelligent design of a recipe being followed.
Update: You might notice there has been an increase of typos and choosing the wrong word that spell check throws up. I'm having a lot of allergy related eye problems. This is the worst year for allergies here, yet. I'm not the only one who has commented on that.
