Prayer is only an illusion, works for those who have resources or alternates.
What about those prayers from millions who die like ants in Syria, Baghdad, Afghanistan, halo cast or wars.
What about kids who are raped, village girls who are gang raped. Try your rays of hope there.
Prayer is just like a cheap rather free homeopathic sugar coated pill which gives a hope of good but in reality it is neither good nor bad.
The biggest churan ( fraud) in human history.
