Should you worry about alien invasion ?

A few weeks ago some friends of mine were chatting about what to do in the event of an Alien attack. It was a light hearted discussion but it got me thinking. Should you worry about alien invasion?  Then the other day scientists announced the discovery of a super earth that just may be in the right place to have some life. And of course we have all seen the movies. Aliens invade earth, millions are killed and mankind is just able to defeat the invaders by the skin of our teeth.

Well don't worry too much about it. Of all the possible disasters that could befall our civilization this is the least probable one. Mind you if you are serious about being prepared for everything. You can take some comfort in the fact that the preparations you have completed for all the other, much more likely disasters. Are probably all you could do anyway in the unlikely event you find ET at your door.

Lets look at the facts.

1. As far as we know Earth has never been visited or invaded by aliens.

2. We don't even know that aliens exist.

3. If aliens do exist. How would they know we are here. Our radio signals have only traveled out about 100 light years as of right now. That's not very far.

4. How would the aliens get here. As far as we know you cant travel faster than the speed of light. If this is correct it would be really hard for ET to get here.

5. How do we know ET is hostile. Aliens could be quite friendly.

6. Would we have any thing they want? As far as we can tell the Earth has nothing special that you cant find on lots of other planets. The earth is made of the same stuff as the rest of the universe. Aliens are not going to travel all that way to take stuff they don't need.

7. Any Aliens that are advanced enough to get here would be so technologically superior to us they could probably wipe the floor with us. So not much point in worrying about it. Then again. I could be wrong.
