Hutton was not in widespread acceptance as late as the U.S. Civil War era. Physicists believed the Earth to be at most 400 million years old at that time, and perhaps as few as 10 million years old.
That was the scientific consensus in Darwin's era, give or take 390 million years.
Can you substantiate the claims that Hutton was not in widespread acceptance during the Civil War Era? You've submitted information about what the physicists estimated the age of the Earth to be. What about the geologists?
Even taking the lowest estimate of 10 million years, we're talking about an estimate 1600x what the YEC theories said it had to be, and still before Darwin.
The physicists and geologists had different theories, and made their estimates based on different criteria, but none of them had anything to do with Darwin, and they both substantially contradicted the YEC theories.
