[Science Fiction General] What's the first example of science fiction addressing the concept of immortality?

Hi all, I've been thinking about this in relation to religious and spiritual texts that address immortality and was wondering about this in sciencefiction!

From what i've been able find is Gullivers Travels, but from what I remember of the story it doesn't *really* fit in as sciencefiction.

I would assume the *Epic of Gilgamesh.* It's not science fiction--it's an epic--although given the subject material, it could retroactively be considered science fiction in some aspects. The *Epic of Gilgamesh* details the adventures of Gilgamesh as he travels the world in search of immortality.
