Here, listen awhile -- whether you "believe" in your keyboard or not, whether there's a whole State Unveristy full of non-believers who deny the truth of your keyboard's existance right across the street, that keyboard is still there. It is. Not the belief or the non-belief, the numbers of believers, the numbers of non-believers, the number and ingenuity of the torture machines of the inquistors, the magnicence and marvelous edifices and icons of the faithful -- all in support or in denial of your keyboard, will have an iota of difference in whether that keyboard is there or not.
Now of course, to be practical with a mere keyboard and all this religious warfare over its existance it is unlikely for the keyboard to survive. If one side is stronger -- the deniers -- they will destroy it, wipe it out, eradicate it and all memory of it. That just has to happen once in history. It is only a mere keyboard, remember.
And if your side is stronger -- the "keyboard believers" -- why it is likely you would enshrine the keyboard and gold plate it and remove it from the essential and instrinsic thing keyboarding function it was meant to be. Instead you will venerate and adore it as some mystical object too Holy to use. By placing your keyboard on a Holy Pedestal you will have ruined it, destoyed it in a diferent way -- destroyed it by removing it from the use it came into existence for.
So stop "believing" and instead accept the thing for what it is.
