An ice age came, an ice age went...Caveman came and went...desert nomads in the middle east came and went...babylonians, persians, medes, egyptians, greeks, romans and Aztecs came and went...all had their "armageddon' Some wiped them selves out. some were slaughtered in war. Some fell to the march of progress, some to volcano's and natural disasters. All their planning for survival came to naught.
and so too will we. The earth may be chaging its axis, reajusting its size or the shape of the continents... who knows, we have been here so short a time in the history of this planet. I think it has million years cycles
It may happen soon, it may happen a hundred tears from now, but one thing always remains... People. New cicvilizations will rise and one day will fall as well. We cannot hope to change it or survive as individuals. Our lives are no more precious than some aztec farm boy in south america 500 odd years ago either. But humans as a species will go on.
Be concerned but dont worry! I get the desire to hoard guns, food and gold... but dont forget that also makes you a target for others! You aint got anything of value? maybe you stand a better chance in worse case scenario.
