ha. the odds are there is life on other planets. actualy, im going to say that there is life on other planets, whether we recognise it or not, or whether it is based off of the same material/needs as us means nothing. eventualy the world will be destroyed, but who knows what by. and who knows if we will have found a way to create another earth to replace it with humans, but in another, younger, galaxy. stop worrying. and as for natural disasters, they happen. there isnt anything that we can do at this point so stop worrying and let it happen, its less painful that way.
A typo. :)
