Arguments From Absence Of Evidence

The following is part of an excellent discussion between Farrell Till and a Christian, Paul Smith, on when absence of evidence, where there should be evidence, is a good argument against a claim. From the alt. Bible. errancy Yahoo group, May 21, 2000:

TILL (1)
Kent, you and David Sparrow need to put your heads together. The two of
you, working independently, have yet to provide a sensible explanation for
this absence of evidence that should be there if these [Exodus] wilderness
stories are historically accurate.

SMITH: (2)
Woah! ...does this mean that arguments from absence are now
considered weighty here? Cool! Someone please let me know,
'cuz I have a BUNCH of arguments from absence that I think bode
well for the God Hypothesis -

TILL (3)
Now, come on, Paul, you have to know that the absence of evidence
where evidence would have to be if certain alleged events had happened
is a compelling reason not to believe reports of the events. If someone
tells you that a flash flood swept through Podunk Valley last week, what
are you going to conclude if you go to Podunk Valley and see no evidence
that would have to be present if such a flood had occurred? This is so
simple that you can surely see it. I'm sure that if you saw absolutely no
evidence of a flash flood, you would view with suspicion any claims that
the civic pride in Podunk Valley was such that everyone had worked
diligently to clean up and repair the damage and that this is why no signs
of the flood remain. You would know that such would be too unlikely
to believe.
