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?

I feel like it goes back to the old saying, “You can’t prove something doesn’t exist.”

We haven’t explored but the merest fraction of space. We have no idea what’s really out there. Just because we haven’t found any evidence of aliens yet (and some people would argue that point), it doesn’t mean aliens don’t exist.

They could be so far away that we’ll never find them within the Sun’s (or Humanity’s) lifetime.

They could be completely uninterested in us.

They could be under some sort of Prime Directive to leave developing worlds alone.

They could be so foreign in nature that neither species would recognize the other as life.

They could be warlike, and keeping ratio silence until their fleet arrives to exterminate us.

They could have more pressing concerns with their own civilization they are trying to work out before contacting us.

You get the idea.
