I am so sick of hearing from theists that god is everywhere and in everything etc. All of those fallacious assertions just prove that your beliefs are as pliable as a fictional novel. You can make the main character be what you want him to be. The thought of a personal deity that cares about your needs and listens to your prayers is absolutely ridiculous. By stating that prayer changes things then you are in essence stating that gods plan is changeable. It is arrogant to believe yourself above all other species on this earth simply because according to your scriptures god chose you above all of creation.
Your god is everywhere because you believe that he is and what you believe is entirely subjective and not evidential. From an objective point of view god does not exist and cannot exist due to the impossibility of one creature or being having so much power and absolute knowledge about everything. People point to the complexity in nature and the so called order of all things but in reality there is lots of chaos in the universe along with the apparent order you claim to see and attribute to god.
