The Watchmaker: my fav argument

[Mister Agenda]

Shifting the burden of proof. This is a fifteen yard penalty and a loss of down.

I'm a science student not a law student. We falsify things in science not prove them beyond a reasonable doubt.

For falsifying something to have any scientific relevance, it must be falsifiable, at least in principle. There is no property a thing could have that would render it 'undesignable' in principle. It's not valid to make up a quality of 'undesignability' just to be able to make a coherent sentence that something with that quality would falsify design.
