A 2010 Gallup poll found that 40% of Americans believe that “God created humans in their present form within the last 10,000 years” [Newport2010].
A 2009 poll found that 39% agreed that “God created the universe, the earth, the sun, moon, stars, plants, animals and the first two people within the past 10,000 years.” [Bishop2010].
And since this favored 'date' is the only one that's trumpeted by the media it is the only date that many assume to be correct.
(By contrast and more representative of OECD, about half as many Canadians espouse such beliefs [Science2.0].) Such notions are, of course, vastly different than the findings of modern science, which pegs the age of the earth at 4.56 billion years, and the age of the universe at 13.75 billion years.
While there are numerous experimental methods used to determine geologic ages, the most frequently employed technique is “radiometric dating,” which is based on measurements of various radioactive isotopes in rocks.
This is the key to figuring out how much time has passed since the rock solidified.
It’s another in our series of roundly discredited theories, myths, and rumors — ones that have pretty much no leg to stand on, but still, despite this fact, continue to be believed and propagated by far, far more people than we would like to admit.
