I agree with descartes Logic that Believing in God is built-in in human psychology and
that's the reason God will ask unbelievers!Regarding Unicorn and other imaginable things
it's result of our own thinking!And we can sketch(draw) them on paper & they have nothing to
do with God ! which cann't be sketched!Its Definition Suggests.
Further,We cannot even stop ourselves from thinking,even for milliseconds then Why arrogate(given) thinking against Our Creator?.Certainly Creator has given us Thinking!Not So?
