Extraordinary claims need extraordinary evidence. Extant Hominids are somewhat more likely than real leprechauns... The existence of those eyewitness accounts

Extraordinary claims need extraordinary evidence. Extant Hominids are somewhat more likely than real leprechauns...

If tens of thousands of people going through those forests all said "nothing there", then that would be negative evidence.
