Dear christian, imagine the news paper carries the headline " New tablet can make people invisible" imagine this news is also on every major news network, imagine your own family are all talking about this new tablet excitedly, Imagine your most trusted friends and colleagues claim to have seen this tablet make a man turn invisible, imagine every single person you talk to speaks only of this new tablet capable of doing this. So i must ask, do you yourself believe in this tablet? do you just accept that its there without ever seeing any proof of it whatsoever? Surely not? surely such an extraordinary claim would require extraordinary evidence?
