I'll start with a spoiler: UFOs are, indeed, real.

In the sense that there are plenty of sightings of objects in the sky no one in a position to know can immediately identify. Hence: Unidentified. Flying. Object.

Now, whether some of these - like Tuesday night's East Valley event - are not weather balloons or flares, but E.T. coming by to snoop on us … that's the bigger question.

So, what do you think? Are the aliens among us?
