What's the point of living if it's not going to go on and on and on and last forever? - I really don't get that question. Why does something have to last forever for it to have meaning?

I would say a disadvantage is that you don't appreciate this one life, you put things off, surpress your desires. You live for another life and not this one. 

I am Muslem so I believe in after life. Allah creat us from nothing and now we speak, think, work . Because of this its easy to live another life after our current life. I know there is after life and this give me a purpose to live . What the purpose of the life if there is no after life? I know that there is many people ask this question. For me , its clear

Yet you resurrect a two month old thread? :P

i believe that there's ressurection day where all the humans will gather in one place and some will be punished and some will live an eternal life in paradise and there won't be another death

Brother, I'm muslim, there's only one thing to believe in. We're all waiting for Jannah, in shaa Allah! :D
