Fine, it is a pattern. Define the difference between a pattern and a design.
What makes it "design" to you?
You're the one pressing the "intelligent design" idea. You tell me, how do you define "design"? What part of the universe exhibits signs of design? What are the designs? How have you eliminated the possibility that they were created without an intelligence's participation?
That is analogous to the fact that it is exceedingly improbable that you and I are here in this world today by random processes, and the observed fossil evidence, chemistry and known physics says that too. Of course, one may "believe" (btw "belief" is something I avoid) that mere possibility, not matter how exceeedingly unlikely is preferable to acceptance of an Intelligent Designer, but to accept such an exceedingly exceeedingly low probability chance I find, well, irrational.
