If people are real, how much more so our Creator – how do you know someone is real? – Because you see them – but what if someone spoke to you on the phone, would you imagine they are real? – well, if you know that a. the Creator both created and spoke to people – He may not be limited to the physical, but the fact a voice can speak is far more conceptual (in fact when I taught in the linguistic department in KU, I asked a professor how do people learn to speak? and he whimsically said "we don’t know")
