At the risk of immense ridicule I have to say I tend to go with the after life concept, but not necessarily in the context of established religion as such. There are two main threads to that one being the purely scientific issue of the destruction of matter, i.e. you can only convert it into energy or a different form. So your mortal remains go on after you are gone and you can follow that thought quite some way. However perhaps the more meaningful is the passing on of genes and acquired attributes from parent to child.
Its taken a long time but I've come to the conclusion that the meaning of life is summarised by its a relay race, and the deal is you just try to pass the baton on in a better place then when you received it.
That is all
