I have you loud and clear.

Hello.

Hello.

Welcome.

Science.

And that is the say physics, medicine, nature.

Space, time, brain, life, the universe.

This week is anybody out there, or are we alone in the universe?

We ponder one of the fundamental questions of humanity.

From flying sources and UFOs to why we haven't found any evidence of aliens, and what

would it mean to find them? I'm Gray Jackson and this is the

Naked Scientists. The Naked Scientists podcast is powered by UKfast.co.

Now picture this. You're out walking the dog.

It's late afternoon and getting dark.

In the sky you see a bright light.

Is it moving? You think so. You try and think what it might be starting with

the most likely. Aircraft landing light, Venus, FOIL balloon reflecting the light, Iridium satellite flare? Could it simply be

floaters in your eye? You're close to the nearby military base. Perhaps it's an

exotic aircraft or one of those drones we hear so much about these days.

Suddenly it dawns on you.

Of course it must be an alien scoutcraft from the Zeta Raticuli star system piloted by three telepathic greys with the tacit approval of a clandestine Majestic 12 US government group.
