There are a few folks like Todd Wood that have been identified as “honest creationists” with the most famous perhaps being Richard Dawkins’ quotes about Kurt Wise:
try as I might, and even with the benefit of intact margins throughout the pages of Scripture, I found it impossible to pick up the Bible without it being rent in two. I had to make a decision between evolution and Scripture. Either the Scripture was true and evolution was wrong or evolution was true and I must toss out the Bible. . . . It was there that night that I accepted the Word of God and rejected all that would ever counter it, including evolution. With that, in great sorrow, I tossed into the fire all my dreams and hopes in science… Although there are scientific reasons for accepting a young earth, I am a young-age creationist because that is my understanding of the Scripture. As I shared with my professors years ago when I was in college, if all the evidence in the universe turns against creationism, I would be the first to admit it, but I would still be a creationist because that is what the Word of God seems to indicate. Here I must stand.
There are also admission as captured by this BioLogos article:
Given the present state of the evidence, they (Paul Nelson and John Mark Reynolds) “admit that as recent creationists we are defending a very natural biblical account, at the cost of abandoning a very plausible scientific picture of an ‘old’ cosmos. But, over the long term, this is not a tenable position.” Thus, they call on their fellow YECs to “develop better scientific accounts” in order “to remain [a] viable” view.[3] Unfortunately, I see no evidence that this is happening.
I don’t think it is possible to make a tenable YEC cosmology for example without accepting that God made the universe to look old and when we measure and calculate its age, it just so happens to give us 13.8 billion years or so.
