but i don't know what will i meet afterlife , maybe other people don't know too
I don't believe in afterlife, and therefore I don't believe that heaven and hell exist. In my opinion, heaven and hell are myths propagated by adherents of various religions, to gain followers. For example, Christians claim that you will burn in hell, if you don't accept Jesus as the saviour. Muslims believe that you will go to heaven and get 72 virgins, if you fight to defend Islam.
so what you do not have confidence ?
if you put it like that ,
then what you know after we are gone?
where do we go?
