I do believe I've read that Darwin at one time studied (thought) to become an Anglican clergyman.
It would be consistent with that early life to return to the faith later in life. There is a spiritual poverty in evolutionary theory that naturally leads to despair and hopelessness.
I hate to think of anyone spending eternity separated from God.
All that, however, doesn't make the story of any conversion true. It sounds like his daughter's would be the best account.
[...I hate to think of anyone spending eternity separated from God...]
My Aunt was about to die, knowing she was not a believer I
asked her where she thought she was going when she died.
She said she believed she would turn into dust. I opened
the Bible she gave to me (it was not hers, but was a
family heir loom, she thought appropriate for me to have),
and read John 14:6 "Jesus said, I am the way, the truth
and the life and no one comes to the Father but by Me".
Unfortunately, her daughter felt I was being insensitive
and became very angry with me. We made up later. But how
could I not try? I love my aunt and hope she made a
decision for Christ before she died.
You do know, don't you, that John Paul II supported evolution?
I don't think I'd call him full of "despair and hopelessness".
