I didn't say it was. I said it was an argument against random mutation and natural selection. Design isn't the only alternative. And, for the record, the stickers which are the subject of this thread say nothing about design.
Therefore complexity does not prove design.
A mischaracterization of the argument from complexity, which I can only assume is deliberate.
I would not say these processes are completely random. Mutations, at the fundamental level, are chemical in nature. That means they are subjected to well know chemical phenomena and such mutation happens in every living thing including you and I. The problem with the stickers is that whoever wrote them doesn't know what science is and isn't qualified to comment on the subject.
