Lack of tangible evidence doesn't always mean it didn't exist or didn't happen. There is always something new to discover. Short-sightedness or lack of observation is not a good quality to have in crucial work of this nature.
Absolutely, in fact many of man’s greatest discoveries were/are made without the aid of evidence – ie the chance discovery of penicillin from an already discarded, contaminated Petri dish. My favourite, though, the chance discovery of aniline purple in 1856 by the 18 year-old scientist William Perkin. Why favourite? Because a colour, notoriously difficult to produce and one restricted to the rich and powerful, had now became available to all.You could say that about many of the things we discuss here :-)
