So this is where it all started. they cba to write anything after the year 2012 on their map (made centuries ago) so everything is gonna blow up and we're all gonna die? yeah sure.
2. Sun Storms
Can you predict sun storms which are gonna occur in 2-3 years? no you cant.
3. The Atom Smasher
They are already doing this, search for the large hadron collider, they have been smashing shit together for years.
Smashing protons and neutrons together will give you quarks, anti-quarks, neutrino's and loads of other shit which no1 cares about... Physicists have been doing this for years.
4. The Bible says...
The bible is a book filled with bullshit, sorry to all you religious folk, but the bible is a story book about a little boy named jesus and some other crap which no1 with half a brain cares about.
5. Super Volcano
Oh noes earth is gonna burp! more nonsense, maybe they are predicting an earthquake, but according to predictions it wont do anything too serious.

Next thing they will say is "we have made the world's first time machine which takes you 1 second into the future! oooooh"
