The Day of the Nefilim

Consider the world that would exist if the best of the New Age theories were true. All the hippy, pseudo-nazi new-ageisms like the ascension, 12-strand DNA, the photon belt and the three days of darkness... imagine that they're all for real, and not just an excuse to fill the shelves of those irritating shops that have crystals and those feather dreamcatcher things in the window and smell of cheap incense. And imagine if those scrappy little pieces of quartz really did have all those properties? The implacable New Age... no matter how much common sense you throw at it, it just keeps coming...
We can't forget conspiracy theories, of course. There really are Nazis on the Moon and at the South Pole. How could there not be? Plus the one-world government, the secret prison camps, Mount Weather, black helicopters and the deals with the aliens...
Oh, the aliens... the Nefilim are around, and everyone from Sitchin to the Secretary-General of the UN knows that. There's Marduk (their home planet), the genetic manipulation of humanity, and the mutants that have survived underground for millennia... the Earth is riddled with underground catacombs. There's a whole world down there, populated with the detritus of the genetic program with which the Nefilim created humanity.
The Nefilim are not only very much alive and well and waiting for their home planet to approach Earth, but the UN, that august body charged with the betterment of world peace and human rights while paradoxically being comprised of the world's governments and led by the planet's leading arms-producing nations, has got other ideas -
"Let's use the threat of an alien invasion to justify the imposition of total control, and we can finally use all the wonderful measures we've been quietly cooking up for years." (There's an idea that would just have to be fiction.)
... but you get the idea. How can so much stuff be true and life go on as normal?
