Dr. Wile does hold to a young earth position. He has repeatedly said so himself on his blog. Sometimes on his blog he mentions some studies or quotes from scientists that do not come from a young earth view. He will usually mention that he doesn’t think the evidence supports an old earth view and give his reasons why. If he doesn’t mention it in the actual blog post it usually comes out in the comments, because someone will ask his position on the age of the earth.
