Why people refuse to believe God exist

There are alot of Christian topic being formed all around but no one has yet said their reasons why they don't believe in God.

Is it just because you can't see God that you feel he don't exist, or because you feel nothing should be greater than humans, or you don't just want to believe God exist?

Are you match with God , to challenge him ?
you are just a creature , who God created you .
Its like a bottle challnge the potter for a fight .
Also God is logic , and your challenge request is Ilogical

I believe in God . And I have nothing that proves that GOD IS NOT EXISTS
I believe in earth moves round the sun and Oxygen and manyother things .
I never seen earth moving round the sun , but I believe it
and same as Oxygen
But I can see its effect on me .
I can see All existances around me .
Flowers , humans , trees , and manyotther things .
Which surely have a creator .

Once someone asked Newton , I don't believe in God
New did not answer him .
After a few days . New made a simulation of galaxy
and invited him to see that
That was a simulation model of galaxy
His friend asked NEW ,,, Wow , did you created that ?
New replied NO
His friend said . WHO created that ?
NEW said , No one
His friend said , Its impossible ... If no one created such a thing . It surely have an inventor

NEW replied " Its a little model and a simple one of Galaxy .
You can not believe that no one created this .
Now , how do you believe that The real Galaxy and cosmos , have no creator ?
