It's just another lie perpetuated by christians, rather like Darwin's
deathbed refutation of evolution, or the lies about Pat Tillman's behavior before his death in Iraq.
I'd like to add to my last comment that first the myth that darwin became a christian and gave up his own theory is most likely fiction and propaganda for christians to call heresy on a christian boogeyman, but secondly in that myth it says that darwin renounced his own theory on his
deathbed, thats what cari believes in
refutation, but just because you might disbelieve a theory you came up with doesn't make the theory wrong.
