We do, of a sort, just not in writing. There is archaeological evidence
everywhere. Carbon dating is often done and these estimates are sometimes
accurate within 50 years. Perhaps this approach could validate (or
disprove) the estimates of Z. and others. I believe this to be the case in
Bulgaria, for example, with the proto-Thracian homeland near Nova Zagora,
which dates to the same estimates as Cruciani 2007. That is a valid,
unbiased piece of evidence.
