Well..., actually this theory may be just as falsifiable as most Intelligent Design ones.

In most inteligent design theories the final piece of evidence to prove o disprove it is easily available after you're dead.

In the case of this model, we probably won't get detection methods good enough to create a less biased sample space until after those of us alive now are dead. So, all in all, we should be able to answer both questions at roughly the same time :)
