The only concrete and verifiable evidence I've personally read about in the survival of death field,is the Myers communications.
They are fragments, sent to mediums on disparate parts of the Earth, which, when put together, reference an intelligence still operative after physical demise.
To my recollection, Myers said he would do this before he died to this world.
It's all very unsatisfactory, now long forgotten in the mulch of the televisual swamp the bulk of the populace has buried its collectively hypnotised head in, trying to find sustenance in a tv trash skip like a flock of flamingoes, but hey, it remains incontrovertible.
The evidential material is available in the records of The Society for Psychical Research.
Oh oh, watch out for a sudden disappearance of material.
Many people have trod the same ground that we walk on, all with hope and perception. No change there then. Is someone taking the piss?
If you encountered a Durotriges warrior from what is now the Surrey/Sussex border on a holiday ramble, the gulf between your global corporate television shaped world view and his would be comical.
He might have the advantage of it.
Is our perceiving intelligence at the centre of a circle of time, chucking us out into various time zones, for experience and laffs?
