It seems to me that humans will convince themselves of any old tosh to avoid confronting the reality of actual death and the ultimate pointlessness of our existence. Little wonder, as it's not a pretty thought. It's time we grew out of it and started facing our responsibilities, i.e. future generations and the state of the planet.

By the way, if you know how, it's frighteningly easy to plant false memories in people's heads which are subjectively indistinguishable from the real thing.
