Is there afterlife?

Most atheists believe there is no after life, just because they see the bodies of dead people vanish after death and are no more valid for being alive.
If you are aware and convinced that every statement should be falsifiable to be valid from practical point of view. So is this statement "My awareness will vanish after death" falsifiable or not? It is apparent that it is not falsifiable, right?May be one says, but also the opposite statement "My awareness will continue after death" is not falsifiable too. I say yes, this is right, so at least you don't have mental proof or disproof for afterlife. Then if you are told that you will have afterlife by a book that claims, it is from God and this claim is augmented by a lot of evidences there is no human being can author a book (Qur'an in specific), then, there is reason to believe in afterlife.
