Do you believe there are aliens?

There must be aliens. Even if they are bacteria in the farthest away planet of the Universe, it would be much improbable that we stand here alone. Or that God created only one planet with life and millions deserted.

Though the video at the link is way cooler.

That is a cool video, even if it were just the video of the CME hitting a moving Mercury.

So that no one thinks I am a loon, I was talking about life of the bacterial or non-intelligent variety, potentially living under the Martian surface and expelling methane into the atmosphere, or under the iceflows of Europa, or heck, some crazy variant of life beyond our own expectations of what life is, basking on the shores of Titan's methane lakes.

We should really, really send something to fly by and pick up some of the water ice spewing from Enceladus, another candidate.

Even if there was life found on Mars, Europa (or anyone where else in the Solar System), we'd first need to rule out that the life form shares common descent with us. If it doesn't, we have a much better grasp on how rare life should be in the universe (we know two abiogenesis events have happened); if it does, then we know some aspects of panspermia are correct (life can survive inter-planetary trips).

You mean we did not send the fact that "we have nukes: stay away"? Instead we sent them a picture of a funny looking man with a dark mustache?

I think they've disprove that theory. Radio signals would have fizzled out and become incomprehensible after leaving the Kuiper Belt or something.
