It's International Skeptics Day: Believe it or not!

Non-believers, conspiracy theorists and Doubting Thomases will get a kick out of today’s holiday. Then again, maybe they won’t. But believe it or not, October 13 is International Skeptics Day. Or is it? While there is not enough concrete evidence about how or when this annual “holiday” began, International Skeptics Day is also celebrated on January 13th and/or the first Friday in January.

Skeptics are folks who doubt the truth and question the validity or authenticity of something most believe to be factual. For instance, some skeptics question the validity of global warming despite claims made by experts in the scientific community. Other skeptics do not believe we ever landed on the moon and the famous images of the moon landings are fakes.

Some refuse to believe President John F. Kennedy was assassinated by lone gunman Lee Harvey Oswald while others believe the late Princess Diana was murdered. And some wonder if Elvis faked his own death? And some people believe the horrendous terrorist attacks of September 11, 2001, were part of a conspiracy. Whether you are a believer or a skeptic, check out Area 51 and the controversial incident that took place in Roswell, New Mexico back in 1947.

So, is it wise to automatically believe everything we are told or is it better to question? What do you think?
