If there is nothing after death how do we find out?

Actually, I'd guess otherwise. The biomasss on this planet in some ways is part of a layer of matter, much like the phototropic zone in the seas, in which matter is more likely to remain in a thin layer, than distribute randomly throughout the available mass. Still, though, the amount of that mass which is biological, much less complex multicellular life, much less one branch of rather large animals, is an extremely small fraction of the entire mass circulating. (And also taking into account that much of the history of our matter, there were no life forms to be a part of.)

In some ways it reminds me of the silliness of past life regression. Mary Roach delves into it in her book Spook, which I unfortunately was too ill to read when required, but given her enfant terrible humor, I'm sure she skewers all the obvious targets. In particular, everybody imagines their past lives to be filled with significant and interesting people. Given the ratio of remarkable people to general sods and idiots, such a high ratio of excellence is surely improbable. But no past life maven regales people with tales of their lives as ditch diggers, accountants, and petty criminals who died in obscurity. It's worth remarking, for those who are not aware, that the Church of Scientology preaches past lives, in addition to all the space opera, and the past life stuff isn't hidden in auditing level OT III.

In the spirit of Darwin, I'd have to surmise that I spent an inordinate amount of time as parts of trilobytes before I made it to the big time of being indefinitely recycled by a community of dung beetles.
