Darwin was a Christian, in his autobiography that was written before he was on his death bed, he was not a Christian, But on his death bed he converted to Christ!
A very smart atheist, eternity is forever.
Darwin claimed to be agnostic, not an atheist and I can find nothing documented that he "converted" to christianity on his deathbed...even if he did does that qualify him for heaven after leading a life believing different? Sounds like a strange religion to me, kinda like the muslims, convert or die...
