In the end we all die!

Quite Ironically In all religions there is a talk about end of life as we know it, Dooms day as we say it, No matter how often we believe our religion is different from other but when it comes to basis there is always a talk about flood from which we all survived and one day we all will die as by Mesopotamian its suppose to be happen by 2012 well I am not here to challenge it too afraid of fate I guess but this has been question which is generally asked around why all religions have similar notions why all religions states one day we all will die, If you ask me our earlier version ancestors as we call them were really afraid people and I am not saying we are any different well more than 10000 years have passed and we still continue to fear the same thing God, something which has been mis-belief of people for all this time, The fear that god might take everything away and well will die, I am not atheist as stated above too scared to challenge fate, god but somehow I believe the notion which is so common among us is nothing but a fear that a child has when he gets a toy he clings to it all the time he can especially when its new because he is afraid he might loose it or someone will take it away till he start realizing no this is his own toy and no one will ever take it from him he starts too loose importance of it and from their its down the hill eventually time passes by and day he stops caring about it at all its gets lost but my story isn't complex as this we humans been always afraid of death no matter how much we deny it no matter how crazy are we there is always a fear that says once we die our potion is over and nothing is left so anyhow we are scared of death I am not talking about some people who don't what life is and just die one day but normal human beings who clings to life as much as he can though he knows he might die one day. this is same fear which had lead to our ancestors to believe this might all end one day and everything as we know might end, I am not saying this is wrong of course earth will end one day but I am pretty sure we would be evolved enough by that time we moved to some safer place until or unless somehow people scared of going against religion and don't move to another planet when earth is about to end but any-who i believe we will be evolved to survive end off earth might even of solar system if to take a long shot move to another galaxy if milky way is about to be completely absorbed by black hole in the middle but we will die when this universe end if we are unable to move to parallel dimension and thus surviving again and settle in different universe, I some how believe We are here for some long time not just to enjoy life on earth but in universe(again No challenge to gods of any religion) I am just writing my thoughts.
In the end we all die but our death isn't the end and once something ends it means its time for new life new universe.
