Intelligent Design

[God of Mr. Hanky]

You don't make a case for your own position by pointing at the limitations if the opposition, even if they are genuine limitations anyway - which is something else that's only been declared and not demonstrated.

So I ask again: how would you set about testing for this designer of yours?

That's exactly how you compare competing hypothesis. We know that a designer could explain the specified sequence. We don't know that mutation could explain it. You can't demonstrate either in a lab because they both rely on a special, non-repeatable event. Laboratory science can't study historical events

Then in that case nobody has any reliable historical records.

All historical field studies defer to lab analysis for authenticity testing and date validation (got that from the school of James Michener ).
