This is once again a flaw in humans,
"There are more things in heaven and earth, TheDon,
Than are dreamt of in your philosophy"
If there was a big house where God lived and came out to say hello every now and again there would be no need for faith. What would people do is they were 100% sure or even knowingly in the presence of God. There would be nothing, just people waiting for instruction of direction no desire to explore existence.
"The greatest trick God ever pulled was convincing the world he didn't exist"
or was that the devil ?
