Take me to the Debunking Tools!
We've got a "sinking feeling" that some people believe catastrophes are a major factor in the development of human cultures. Volcanic activity has played a role in the destruction of some ancient sites and may even have dramatically changed whole cultures, but there is little evidence of major cataclysms affecting the whole world in the way many wish to believe. Take a look at some of these web sites. Some point to legitimate theory and data, but take a hard look at the evidence provided.

Catastrophic events played a role in
the recent history of the solar system and in the formative phases of
ancient civilizations. Included are Velikovsky's Worlds in
Collision and the Saturn Thesis. Be sure to look at their other resources listing
several print journals that study the role of catastrophism in human
history!
