December 21, 2012? It is NOT a scam. You can think differently, but you won't be prepared when it comes around. I thought this was a scam after I heard about worms falling from the sky, ailiens with 'cyber seatbelts', and the hyperdimention getting messed up. I would never believe that junk (unless it was happening). But what I do believe is NASA. Search 'NASA - Solar Storm Warning' on Google, then go to the first link. Read through it, then message me, tell me in a chatroom, or tell everyone on Twiiter what YOU think.
Acually, in some cases, fire has fallen from the sky. Some how oil mixed with water evaporated into the clouds, when it started to rain the oil somehow caught on fire, so it has rained oil. Also small dead fish and other small creatures like spiders, have been reported to fall from the sky.
