I disagree what you say. For your kind information can you give the date birth of your grand fathers grand mother. or else can you say what is your grand fathers grand mothers name. It will not be possible for you. Giving the details of your family members is not possible for you, then how can you say that there is no Ram or Krishna. Please dont play in religious belief. If you believe that your mother who brought you up has given birth to you is true the same should be accepted. Dont suspect as you are not suspecting your birth
