Доброго времени суток!

Как лучше перевести "real thing" в следующем контексте:

According to a 1998 study in the journal Nature that asked members of the National Academy of Sciences about their spiritual beliefs, about 72 percent expressed disbelief in the existence of a personal god.
Many of our leading scientific thinkers, turned off by secondhand mythologies about a secondhand God that have nothing to do with **the real thing**, have concluded that there is no such thing as survival the real thing, have concluded that there is no such as survival
of the death of the physical body or any form of existence except the physical version we know.
