It is a very difficult question to answer....logically there is no God, since nobody has seen..but when we sincerely ask for something and pray..to our God..and when good things happen in our life..we believe that we do have God/super power.
Since we cannot see, hear, touch, smell or otherwise perceive the identity called 'God', we are left with the only possible opinion that this is simply a myth, hypothetical notion.
God is not a imaginary. If you trust in god, then you will think that someone is watching you and you will try to live a truthful life. If you think there is no one to watch, then you can do anything....
Now do you want God or not? Decide yourself...............
One can not say that GOD exist in real or not and this has been unknown issue.People has constantly searching for God from ancient time. Till now they are some cases which make us believe that god exist but can not be seen. One can only feel him or believe him. So GOd is just a belief and it depends on person whether to believe him or not.
Feeling or testing the presence of God cannot be done by human norms. One needs those norms that will be at par with Him. As one can never reach there, I am sorry to say that people plainly refuse His existence, though it is He who gave birth to all of us.
