Existence of God

No-on can prove beyond any doubt the existence on non-existence of god/gods. It doesn't matter. If there is a god/gods, it is obvious that all those of some sort of religious persuasion are worshipping the same god/gods in their own individual ways, and claiming to be worshipping 'the true deity'. And most of them are doing it in an incredibly stupid way. When you write a book, you write it to store thoughts, possibly to share, but you do it to serve a function. It function is rarely so futile as to hold down the pages of your next manuscript, which you intend to be of some purpose. Likewise, if a God exists and created humans with free will, intelligence and individualism, and he/she/it is truly all seeing all knowing, he would not have created humans for the incredibly boring task of telling him how great he is and paying homage to him. He doesn't need it, if he is infinitely wise, he wouldn't have created us as an overly complicated post it note to tell him he is great, if he's watching to see what happens, he'd no doubt get the shits with the boredom of it all, and be offended that people devote their entire lives to telling him exactly what he already knows.(I notice that I've digressed to he, it's to annoying trying to please everyone with every syllable so I won't, but I don't meant any malice by it) He'd want us to do something exciting. If you put your pet mouse in a maze and watch it, you don't want it to stare at you adoringly telling you how great you are in mouse speak, you want to see it explore this maze and find the limits of it environment. Likewise, if god does exist, he doesn't want us to be the boring mouse paying him homage and ignoring the vast maze he has put us in, he wants us to go out and explore it, test the limits and find out everything we can about our locality.
Now let's take the mouse in the maze situation and expand on it. Now it's a massive maze, monstrously huge, and with a vast number of mice in there(I'll go on to different colours sizes and sexes of them in another post). All the mice are at the beginning of the maze, staring up adoringly at the owner of the huge maze('god'). Organised religion are the mice on the outside who are scared by the vast unknowns around them, and in an effort to protect those mice on the inside of the group, gang up and push everyone to stare up at the big guy. They tell everyone looking out at the unknown areas that they're imagining things and that if they don't stare up at the big guy they're disrespecting him and won't get the cheese in the middle of the maze. They go on about this so much that they convince people that it's the only way it could be. Some mice go so far as to kill other mice that are trying to challenge and push the boundaries. They fight and argue with mice that are staring up at the reflection of the big guy in the glass of the mirror. They fight and argue with the mice that have had a good look at the big guy and now have their eyes closed and are focusing on the image in their minds. After the big guy has wandered off the keep facing the same direction or so they believe, they fight and argue about which direction they are facing, they fight over whether the big guy is still there or whether he's not, they wage mini mouse wars on mice with contradictory opinions. Over and over and over. So eventually, there are big opposing gangs of mice facing different directions, all trying to get all the other mice to face the same direction, fighting and arguing about it even though they really don't understand it. Then you have other mice who never saw what the other mice are looking at and reckon they're all full of shit. Then you have others who try to explore the maze but try and face the same direction as their gang of mice told them to, so their bumping into things, not knowing where they are heading, but feeling safe in the knowledge that they are facing their god even if they've never seen their god, and have only the words of others to go on. They feel really safe and don't care that they're wandering into the cats mouth because they've been good and done exactly the right thing so they know they'll be safe. Granted there are a few mice that have wandered off on their own and done their own thing, and are having a great time, and the god that they're paying no attention to is probably finding the activities of these mice far more entertaining and worthwhile of his time than the activities of the boring mice that are spending their entire time devoting themselves to the idea that if they behave exactly right, then they'll be rewarded. Only to find one day, that they've walked blind into the cat's mouth, and missed out on the cool stuff that their god put there for them to enjoy. You can't get the cheese unless you go looking for it.
Whether or not God exists is irrelevant. If he did create everything, he created EVERYTHING and means for us to explore and enjoy it and not spend our time focusing on him. If he doesn't exist, why is everyone looking for him and not enjoying what surrounds them.
