Any theory that is scientifically falsifiable is scientific. ID can be falsified by several methods. In the distant past, ID was considered to be falsified by scientists because speciation events were claimed to happen slowly, contrary to the prediction of ID for rapid speciation (i.e. a designer introduces a new model car/life form/whatever).
Now that we know that speciation events happen rapidly, ID must once again be considered. The earlier falsification claim was in error, per our fossil record.
In the "distant past" there was no ID. It was called creationism, and it held that the earth was created by the God of Abraham, as literally described in the Book of Genesis, 6000 years ago.
Again - what exactly IS your theory? And why does the prediction of rapid speciation across time flow from it, rather than a prediction of simultaneous creation at a single moment? WOuld you like to provide some citations to peer-reviewed journals or books that would back you up here?
