I agree with those who think that "timeline" questions about the creation of angels or the flood are gotcha questions. Since dates aren't really mentioned in the scriptures, there is no way to get anything other than a speculative answer.
So you'd think.
But evidently there's enough information in Scripture for them to reject actual science, like geology, so if they're trying to play on the same field, they should be held accountable for the same standards.
Geologists can say "This event happened in this location, and at this time," and explain why he thinks this to be true.
If the thumpers are limited to speculation, then they're limited to speculation. But they should be able, like a geologist, to produce the sources they use, and their interpretations, to support a claim that they know more than the geologist does about geology.
It wouldn't BE a 'gotcha' except that when given a chance to compete, they end up hand-waving. They clearly demonstrate that they don't have much of their own, except as a reaction to, and rejection of, actual knowledge.
