Life And Death..

i've been doing some deep thinking today about what happens to us after we die, and yes i've considered heaven and hell, but i've come to a logical conclusion..when we die, we just disapear, we go into an eternal sleep never to wake up again, and for as long as the universe exists, our life is like a rabbits heart beat..it comes and goes without a true purpose...when we die, this whole world will go on without us and we'll never have another chance to exsist ever...so what we do now is the only chance we ever get to make decsions, like who we spend the rest of our life with when we marry, or what we do with our lives, after those descions are made, and we die, we'll never get another chance to make them again...we'll be remebered by others for a few generations if we're lucky and live in peoples memories, but after that, we're fogotten completly, this world goes on for billions and billions of years without us, we're just just a drop in the bucket that'll soon evaporate..and while this world goes on, we come (born) live a short pitiful life (the only chance we'll get to live one) and then  we go (die), come and go...and i dont wanna affend anyone one, but after logically accepting the fact that we're gone when we die, i realize that heaven and earth we're things posibly made up by people who didnt wanna accept the fact that "death is the end of our existance" most people cant accept that and shouldnt have to, i cant even accept it, i dont wanna just live for awile with no purpose and then disapear never to come back ever ever again...so you can choose to believe that "When we die, its only the beggining" (like the egyptions) or...when we die, we come back in a different form (reincarnation)...or maybe there is a "god" somewhere out there,and we can either go to heaven or hell but how do you know which one is real? u can choose to believe that your religion is the rightful one, when other religions feel the exact same way..what if u die believing in the christian god, when buddah was the rightful god?  truth is, i really dont know or cant say for sure, but for now...i'll just accept death as the end of our existance here..and if you think about it, life is sooo pathetically short...and unfair...we spend most of our time wasting our only chance to exist by doing nothing...and i mean nothing by not making a difference, not even a dent...we waste our so much of our life by fighting (war) and we have our life ruined by so many people like child molesters, or by idiot murderers..(who have probably realized they can do whatever during their life, so they dont let civil rules apply to them) so when someone tells you to make the best out of your life  ..you should actaully consider doing it....cause we'll all just be gone some day, theres really no easier way to narrow it down....we'll never get to see  what fascinating discoveries humans make in the future, or the way life will be...we'll miss out on so much. and life will just go on without us for billions and billions of years.
