Why we will never be invaded by posh aliens

"Earth-like planets may be common

Earth-like planets orbiting other stars may be far more common than had once been thought, a study suggests."

This is a rather disapointing news story. I'd always hoped that when we were eventually invaded by aliens it would be in a stereotypical British tourist kind of way.

Posh Alien: Hallo? Do you speak alien? Awfully pleased to meet you. What's the local cuisine like? Really? I'll just have chips.

You know, just to see how we would like it.

The idea of other planets being common is quite scary. Who would want to be invaded by a bunch of chavs?
Then again it may be too late to worry about. They're aleady here...
