For the sake of sanity, Atheists default to zero unless extraordinary evidence comes along to argue for putting a one there.

As Pascal pointed out, and as atheists love to dismiss, the wager is our senses are able to grasp all the evidence there is.
If our senses and mind are provided limited but sufficient evidence now to make a choice, and the extraordinary evidence only comes along after it is too late to make a choice then atheism is not quite as reasonable as it would seem.
I have many times missed the evidence for things right in front of me and clearly sensed the evidence for things which weren’t there at all.
The things that weren’t there did me no harm. The things that were but that I disbelieved often did.
