This logic is not sound. Why couldn’t be the case that only one religion is right?
Three people looking at a triangle might have different opinions about what shape it is. It is inconceivable that they are all right, but that does not imply that they are all wrong.
Say I have 6 people all guessing a different result of a roll of a D6. It’s inconceivable that they are all right, and it’s absolutely not a “reasonable conclusion” that they are all wrong.
Additionally, if we include the people who believe they know there is no god (a position held with no proof) as a religion (which is not much of a stretch) then it’s also included in the " they are all wrong" group.
I lack a belief in a god because I’ve been provided no evidence that own exists, but the logic in this picture is full of holes.
