I'm not religious, I'm just going off what others have said. Like in one sci-fi novel where a human meets an alien who has been observing humanity for a while, the human asks "how long does your species live?" The alien replies "three score and ten, just like your God allows you." Or something else that went along the lines of "modern humans had added a whole extra score to the three score and ten God originally allocated us..."
Uh-huh, then how do you cope with the fact that Star Trek has shown at least two humans who have lived to be 140?
It was a speculative opinion expressed by a group of scientists.
