38 Things Older Than 6,000 Years, A Primer For Young Earth Creationists

In the spirit of attractions like Ken Ham’s Ark Encounter, the white elephant project celebrating scientific illiteracy, it might be useful to have at the ready some fact-based talking points should you find yourself in a conversation with a Young Earth Creationist.

Here are the various ages of 38 things that I think are pretty darn awesome. Estimates here are of course based on the latest science, so being based on good science they are subject to adjustment with better evidence. Enjoy!

R.L. Paine is a writer, activist, and science lover. We all need to find a bit more Hitch in ourselves. “Beware the irrational, however seductive. Shun the 'transcendent' and all who invite you to subordinate or annihilate yourself...Never be a spectator of unfairness or stupidity. Seek out argument and disputation for their own sake; the grave will supply plenty of time for silence...” - Christopher Hitchens
