& such questions about inference don't just have to do with
the past. Do we know that there are _really_ electrons, pions, &c? So
some YECs find themselves allied with those post-modernists who think
that scientists have simply "constructed" quarks &c instead of
discovering them. & there is _some_ truth in that - as long as you
don't think that quarks are _entirely_ a construct, no more or less real
than elves and trolls.
