Aliens - The good, the bad and the ugly

There are more people in the world who believe in the existence of other forms of life outside our planet than those who believe our planet is the only planet in universe that supports life.

Aliens are usually imagined (particularly because of Sci-Fi movies) as technologically superior monster-like creatures whose only goal is to collect the resources of our planet and in the process wiping out everything that breathes including human race.

The bad yes, the ugly also yes, the good not that much at least this is what most people think about aliens. If aliens really decide to pay us a visit then we should pray that they are completely the opposite of the image most of us have created about them.

Lets get real if aliens are really violent monsters with super-advanced technology then we must really hope our planet won't come anywhere near their ever-expanding horizon. On the other hand, if they are on the some sort of philanthropic mission towards the less intelligent creatures then they would really be welcome to pay us a visit and learn us a thing or two.

But who knows, perhaps when we make first contact we'll be the ones more technologically advanced. Since we know so little about our universe any scenario is possible in this story, no matter how strange it may seem from the first look.

Perhaps aliens have already infiltrated our planet and are waiting for the right time to show their existence to the rest of the world, hopefully in a peaceful manner.

You see my point about any given scenario? Only imagination is our limit when thinking about aliens.

How do you imagine aliens? The good, the bad, the ugly?
