Question

Does believing in god increases the probability that god does exist

Answer 1

KInda if you love him then he loves personally i dont believe in him but thats everyone decision

Answer 2

No.

If he exists then he does. More or less people "believing" doesn't change a fact.

It's like how we can't see all colors and other creatures can see "more" colors than us; and then having us claim they don't exist. Whether we decide to believe there's more colors we can't see or not will not change the fact of whether there IS or ISNT.
