I will reiterate: there are plenty of imaginative concepts at our disposal for which we never attribute the I don't know variable toward their existence. We confidently understand those things do not exist despite the lack of evidence related to their non-existence, which in itself is such an illogical trope that only the simple minded ever feel the need to apply it as an argument.
