Especially with what you've quoted, I believe that to be quite a fantastical hypothesis. It does seem farfetched.
But given these reports as well as the Vatican's recent discussion on accepting extraterrestrial life, maybe there's something to it after all.
I can only hope that, for some time at least, all the rumours and conspiracy theories are put to rest, whether in favour or in opposition to the existence of extraterrestrial life.
Of course, I'm personally biased towards the probability that they exist, but I really wouldn't expect such contact and communication between species and interstellar travel, more of the bacterial or simple organism variety on Titan or Europa or even the Moon or something.
It seems real life never really has much in the way of explosive revelations. If we do find extraterrestrial life it could be of the form "Yes, we've confirmed that microbes exist on this ice comet in simple silicon based strands" and not of the "So, look up in the sky and you'll see the gigantic flying saucer zapping people with a green photon beam of indeterminate hostility" variety.
