Exactly. Turns out science is not good at all at testing intermittent or one time events that are localized and in the distant past.
You know, things like a single de novo creation event, Jesus turning water to wine, the Virgin Birth. These things, even if they are true, are not expected to leave any physical evidence. The only evidence we might expect is a change in the behaivior or recorded thoughts of those downstream from such events. Now we are moving out the natural sciences into historical study. Science cannot really adjudicate these claims, even if they are real and even if they are important to understanding how and why history unfolds the way it did.
