"Grandma went to heaven" is a statement of fact about a very specific matter that is either true or false. The person uttering it has not seen, heard, smelled, or touched a single piece of evidence to verify this supposed fact. Indeed, they're saying it either because they're sincerely repeating a myth they've heard since they were credulous children, because they want to mollify a grieving child's anguish, or both. If you make a claim about the physical location of a human being, yet you have absolutely no evidence to bolster your claim, then you're making a claim that is not falsifiable and should be considered false.
