Many ancient humans cultures have similar mythology, and all humans have a seemingly innate desire to hoard gold, silver, etc. By 2011 we've stacked most of it up nice and neat into vaults ready to be picked up. Many of these ancient myths point to around 2012 as the date when "something significant" happens.
Wow, that's the hard way of getting gold. Gold is even easier to get in space in asteroids than it is on earth since there isn't any gravity (or extremely little) making it sink to the core. One medium sized asteroid can contain as much gold as all of humanity has mined throughout history. Which ties back to bitcoin, since once we start asteroid mining almost all "precious" metals will become worthless scrap beyond their utilitarian uses. So gold is a bad place to put your money in the super long term.
