The existence of a God is fundamentally impossible

I am a fatalist; I believe in fate and that we are merely a possible occurrence that is one universe in an infinite multiverse and our 'verse' is one of many possibilities. Yet what I have found, both through logical reasoning and research is that any justification for a Deity or God of some kind relies purely on ones urge to want there to be a higher power as opposed to actually offering any logical explanation as to how a God is possible. I am now going to introduce the theory that a God, or Deity, is in fact impossible. Suppose there were an entity (calling God a being would be pointless since it has no beginning, cannot be interpreted by any of the five physical senses and somehow is bigger than everything by infinite magnification) and this entity had control to create whatever it saw fit, to enable any parameters it sought to be applicable to that reality and therefore perhaps create creatures with a systematic mind that can function independently of the God's control. Suppose there was such an entity, something so magnificently powerful that it could create and edit what it created as it wished, now consider that entity's priorities. The God has many, in fact infinite, creations to entertain itself with, Earth is one of them. Humans are probably such an insignificant creation they are smaller than what an electro is to us, to God. Yet somehow the God has overcome its boredom or inactivity by creating a random scenarion with a significantly dominant species in terms of communicational aptitude. It creates two genders for them and has previously created many other animals (whether or not i used evolution to get to the human is unknown but there are suggestible similarities). This entity never began (so clearly the time parameter of existence doesn't apply to it), has infinite height (so the y parameter of existence doesn't apply to it), has infinite width (so the x parameter of existence doesn't apply to it) and has no depth of existence (so the z parameter of existence doesn't apply to it). This entity also will never end (probably because something that never began can never end). It can 'create' energy (another impossibility) and can kill, or take lives as it pleases. For some reason, there are a group of people who believe that this entity has a moral code, which one must stick by to live a happy, fulfilled life and afterlife (life after life defeats the very definition of death but lets not get sidetracked). The true question is that if life is a test and those who follow the right moral code win, why not kill them when they pass so that they can immediately go to heaven, or alternatively why not kill those who fail it. A third option might be killing every person at the exact same age, giving a fair test. Nonetheless, God chooses for no apparent reason to create an unfair test which some people naturally have an advantage at since they are born into a family which introduces them to religion. Yet, it is very clear that both religious and atheist people get diseases, get raped, murdered and stolen from. In the end it merely depends on ones financial situation or their intellectual ability to gain financial security that determines their success in life. Therefore, due to the self contradictory terms in which a God could possibly exist I stand to believe a God is an impossible occurrence which has no moral code since it doesn't test everyone fairly.
