God, as introduced by religions, does not exist.
Yet true God exists—He makes the provisions for enjoyment of life, and gives the management to humans, who in turn begin to worship greed which turns the earth into a hell.
When the body is in a state of well-being, the mind functions well, and it probes beneath the surface, creates poetry, glorifies God …etc. But when the body does not enjoy a state of well-being, or there is some sort of suffering the mind does not see anything other than the physical disturbance or such suffering which obscures his reasoning. That means if paradise had continued till now, and if no religions had appeared to misrepresent God, no one would have thought about possibility of non-existence of God.
