That's only because nothing ever can.
However, if anti-IDers use ID tools (fossil record, transitional forms, experimentation, etc.) to disprove ID, then by logical extension, they have also invalidated the ID tools used to disprove ID.
No one ever answers you on that? Let me be the first to tell you that the use of one's reason to systematically investigate nature does not "invalidate itself" even if it does somehow undermine somebody else's contention that we had to have been zapped into existence by some higher intelligence. Why should it?
In fact, I've already tried to tell you as much on this thread. What you mischaracterize as "ID tools" are not the gifts of Behe, Dembski, etc. nor does their validity in any way follow from the consequences of the rather shoddy work the ID movement has done.
ID didn't invent intelligence, it just misapplied the concept.
