There are two separate issues at play here.
The first concerns the status of "absence of evidence". There is an old
adage that "absence of evidence is not evidence of absence". This view
is warranted, but only under certain circumstances.
For example, consider the following two claims:
(1) There is life in the oceans of Enceladus.
(2) There was, at one point, a large, enslaved, Hebrew population in
Egypt.
In both of these cases, we have no actual evidence to support these
claims. However, in the first case, we have not had any opportunity to
actually look for evidence. We have satellite evidence that there are
indeed oceans under the surface of Enceladus, but we've never actually
been to these oceans, so a lack of evidence is completely unsurprising.
In this case the absence of evidence really isn't evidence of absence,
so one can claim that there *might* be life in the oceans of Enceladus,
and this claim would be consistent with the (non-existent) evidence.
Note of course that just as there is no evidence showing there isn't
life in these oceans, there is also no evidence that there is, so one
cannot assert that there *is* life here, only that there might be.
In the second case, however, we *have* had opportunities to gather
evidence. Egypt is, from an archaeological standpoint, one of the most
extensively researched areas on earth. We've uncovered a huge amount of
data on the various periods of Egyptian history, enough to glean large
amounts of information on their lifestyle, their economy, their
religion, and so forth. But, we haven't found anything to suggest a
hebrew population in Egypt, and because we expect people to leave
traces, in this particular case absence of evidence really does start to
become evidence of absence given enough data.
The only thing that suggests such a hebrew presence is the exodus
account itself, but using that as evidence would be on par with arguing
for the existence of an historical Lady Macbeth based solely on
Shakespeare, or that Raskolnikov really did kill his landlord with an
axe based solely on Dostoevskij. These accounts both reference some
actual people, places, and events, but they also reference many that are
not, and unless something found in these works can be corroborated there
is no reason to assume that it is real.
The second issue involves burden of proof. In general, it is incumbent
on the one claiming the existence of something to provide evidence in
favour of that claim; not for their detractors to disprove said claim.
Thus, were I to assert that there is, in fact, life on Enceladus, it
would be incumbent on me to provide evidence supporting this claim, not
for you to provide evidence that there isn't. Similarly, in absence of
any evidence regarding exodus, it is incumbent on those who assert that
it actually happened to provide evidence of this fact, not on those who
would deny that it occurred.
Without adopting such a position, one is left in a position where we
have to take any claim made anywhere by anyone seriously and attempt to
disprove it. For example, we have lots of evidence that the pyramids
were constructed by egyptian artisans. We have no evidence to suggest
that they were constructed by aliens, or by hebrew slaves, or by the
servants of Cthulhu. But, by your reasoning, we'd have to treat all of
these claims as on par since we don't have any evidence against these
claims, either. But if we were to preoccupy itself with disproving every
claim, no matter how fanciful, knowledge would never progress. That's
why we insist that evidence be offered *in favour* of claims rather than
against claims.
