Thanks. Actually, I’ve been hunting about, inspired by Jonathan’s suggestions, and find that both the authors of “Pandas” are also described as YEC. However, in my edition, there is no suggestion that they think the earth is young - quite the reverse. Although the passage quoted by Jonathan above is certainly present, the rest of that chapter (on fossils) repeatedly refers to things happening millions of years ago, and a table on Page 99 gives the “First Appearance” of Kakabekia at over a billion years ago.
Moving on to Paul Nelson. Googling “paul nelson” “age of the earth”, the very first entry is from sandwalk.blogspot.com. Laurance A. Moran begins: “Paul Nelson is a Young Earth Creationist. He believes the Earth is less than 10,000 years old and all modern species were created separately.” To which, in a comment a few lines further down, Paul Nelson himself replies: “I don’t endorse either of these propositions.” Although he does claim to be a “young-earth creationist”. Weird or what.
The second Google find is from unseenevidence.com. Here we have: “Paul Nelson and John Mark Reynolds admit,
Natural science at the moment seems to overwhelmingly point to an old cosmos. Though creationist scientists have suggested some evidences for a recent cosmos, none are widely accepted as true. […] As it is now interpreted, the data are mostly against us. […] Recent creationists should humbly agree that their view is, at the moment, implausible on purely scientific grounds.”
Hardly a robust defence of a young earth on scientific grounds.
