(1) The man called Jesus the Christ was born 2008 years ago--there was no year zero--your thesis is only correct if we follow the Chinese model, wherein one is 1 year old at birth.
(2) If the Jehovah's Witnesses are correct, the Apocalypse will come in 2012.
(3) The named countries only account for 40% of the world's gold production--the Russians who account for a major fraction of the remaining 60% are notoriously tight-lipped about new discoveries, present production, projected reserves, etc.
(4) Gold is not "consumed" the way oil is--only transformed. Nearly all the gold ever mined is still available, somewhere, somehow, and if prices rise high enough, will be recovered even if the methods are presently uneconomic or repugnant.
(5) All these debts will come due, that's true--but everybody in this present generation will be long gone. I don't see a huge problem near-term, and there are worse problems to be concerned with long-term (antibiotic-resistant diseases ravaging the population and climate-change flooding the Earth for example).
(5) Most importantly, what changes do you suggest? Because otherwise your isolated facts come off as merely insensate* fear-mongering AKA "causing Maalox-moments".
