eli5: Carl Sagan’s absence of evidence

4.71K views

Big fan of Carl Sagan, he was like a father figure to me, I’m partially molded by him.
That said, something he used to say all the time really baffled me, still does:
“Absence of evidence is not evidence of absence”
He said this when talking about aliens.
However: Sagan was a famous non believer.
How does this aphorism reconcile with the existence or non existence of a god?
If “absence of evidence is not evidence of absence” does that apply to a god as well?
Is there a god even though there is no evidence of him/her/it?

It means that no reasonable atheist can 100% completely rule out the possibility of some sort of deity existing.

However, if there is no evidence of something that realistically should leave some evidence, then that is a pretty good reason not to actively believe in its existence even though it is theoretically at least somewhat possible.

So no, just because some sort of deity is theoretically possible does not necessarily mean that it is reasonable to believe in a diety. Certainly not any one of the deities that humanity has come up with since no other human has displayed any sort of viable knowledge about the subject.
