Can you persuade me from Agnostic to Atheist?

[ignoramus]

OK, most dictionaries seem to use the same definition of God below:

1(In Christianity and other monotheistic religions) the creator and ruler of the universe and source of all moral authority; the supreme being.

2 (god) (In certain other religions) a superhuman being or spirit worshipped as having power over nature or human fortunes; a deity: a moon god the Hindu god Vishnu


Rob, anyone? Here is exactly what God is!

Option 1 can be easily dismissed since what we can read of it is so contradictory and paradoxical, and judging by the amount of times it has shown itself to anyone, can be safely dismissed as complete fiction ... It cannot exist as described.

Option 2 "superhuman being" may have had as chance at existing but again, why is being worshipped a prerequisite to be a god? Why must they have favour over human fortunes? So many squillions of planets, and they going to worry about finding our car keys? Nup!

There you go folks ...2 main definitions for the word God and god. Both as unrealistic and ridiculous as each other.

So basically, if I want to explore our possible creator as:
: the alien who had a picnic on earth and wiped his boots on a rock before he left or
: an advanced species who intentionally put us here or even altered primate dna to create a hybrid

then I basically cannot use the term God or god. It's not what it means.
God, as far as theists are concerned can only refer to the skydaddy.

So, now I'm not ignostic anymore. I know what God is. I now know our creator didn't give us our morals and I know he's not intervening in human affairs. 
So guys, is it really arrogant to say we know those only 2 options cannot exist? Why can't we be gnostic atheists?
