Is a Concept of a Designer unscientific?

I don't think that a concept can be considered
unscientific at all.The concept of a designer is not unscientific
(any more than it is scientific) ... it is simply
a concept.Concepts may or may not lend themselves to scientific
enquiry.The concept of a designer is one that, at present,
cannot be investigated scientifically because we have
no framework for such an investigation. We cannot even
identify design in known designed objects without looking
up the design team, so how can we investigate design in nature?

I'm eating a sandwhich right now and I look at it and it gives me evidence of a cook or baker that made it.

The problem is that the sandwich doesn't provide evidence of
a cook or baker at all. Previous experience with sandwiches
suggests that they are made by a sandwich maker of some description,
but there is nothing inherent in the sandwich to confirm
or deny that any particular instance of a sandwich was, in fact,
made rather than just popped full-formed into existence on the
kitchen work-top.An examination of the sandwich edge MAY disclose the use of
an implement implying that cuts were made to the bread (and filling
possibly), there may be marks in the butter/sandwich spread that
fit the pattern of a knife in the kitchen sink or drawer and thus
be suggestive of an implement having been used.We may be able to find evidence of food remaining in the fridge
that has a quantity missing consistent with the quantity of
same material within the sandwich.These evidences may combine to lead us to the conclusion that
the sandwich was, indeed, made by a sandwich maker.The sandwich itself is not evidence of a sandwich maker, however.
