The Ten Plagues of Egypt

It is quite possible that especially severe volcanic eruptions caused a shift in the climate temporarily, many authors have considered the explosion of Krakatoa 70,000 years ago to have been a decisive factor in human evolution.

Homo sapiens before this period were not especially distinguished compared to the other humanoids around at that point. We have little art and artifacts from homo sapiens before then. The explosion of Krakatoa is though to have caused sever climatic change which made survival especially difficult for many species, including these early humans. The Economist estimates that in the aftermath during the especially severe period of climate change, homo sapien numbers were reduced to between 2-3,000. Only the very fittest and smartest of homo sapiens survived, the inferior specimens died out in the newly highly competitive environment. Krakatoa is a huge volcano and the eruption at Thera was also massive. Changes in climate would not be a surprising result, with agriculture severely affected and society itself collapsing due to famine.
