Actally, you can have an answer to that question of creator of God...
Just as you are fed extra knowledge by qualifying (or grasping) the current one, you cannot comprehend the origin of God in this form...
When the atma comes into one with the paramatman... (cosmic consciousness), the truth would be revealed...
If something is beyond comprehension, it is open to perception.. and this is precisely what has given birth to atheists...
You are entitled to your perception... but there are questions which an atheist cannot answer.. so it is the same square for everyone... hold your beliefs and perception with yourself and live a peaceful and contented life...
