Like what? Having a beer with an alien in your front lawn with that dork's flying saucer hovering a few feet away? Even then you'd say that it was all hallucination and a drug induced episode. Mind games being played by the CIA, NSA, HLS and what have you!
You can't win, can you?
Cheers!

Life in open space is not possible.
No food, no warmth, no way to move in the desired direction.
Perhaps you should do your research. Ever hear of a Water Bear? They are tiny organisms that can survive in up to 6000 atmospheres of pressure, which is much greater than that of the deepest part of any ocean on Earth, thay can survive in +200 C and -272 C (around -273.5 is 0 Kelvin, space is 2.7 Kelvin) and can also survive in the vaccuum of space. So before blurting out your own ideas without knowing anything, first do some research. If for nothing else, at least to have some grounds to found your theories.
Yes, Sir professor!
Gigantic space worms are real!
Silly me, how could I question that?

Heres your proof that life CAN EXIST IN A VACUMM and more importantly in space
"We're so dumb about what life is because we only have one example," said astrobiologist Chris McKay of NASA Ames Research Center at Moffett Field, near the city of Mountain View in the San Francisco Bay Area. "It may be true that we sail through the universe and everything we find is carbon and water, but I would hesitate to conclude that based on the one example we have."
As for ammonia (used in smelling salts), it's scarce on Earth, but "you could easily have an ocean of ammonia," Houk said. In fact, scientists speculate that Saturn's moon Titan could have such an ocean. Life could certainly exist at the cold temperatures at which ammonia is liquid (between minus 28 degrees Fahrenheit and minus 108 degrees on Earth). Like water, ammonia is polar, and an excellent solvent. Even if water does turn out to be the beverage of choice for quenching life's insatiable thirst, does that mean carbon has to be in the mix too?
Carbon? That basic component of "life as we know it?" Not necessarily. A diamond is pure carbon, and it may be pretty, but it isn't alive.
What really sets Earth apart is nitrogen, which makes up 80 percent of the planet's atmosphere. And it's there only because there is abundant life on Earth, say scientists at the University of Southern California, who have come up with a provocative approach to searching for life on other planets.
"If there wasn't anything biological on Earth, there wouldn't be very much nitrogen in the atmosphere," says Douglas Capone, professor of environmental biology at USC and lead author of a report in a recent issue of the journal Science. The report grew out of a class discussion two years ago in a course taught by Capone and Kenneth Nealson, professor of Earth sciences.
"It's hard to imagine life without water, but it's easy to imagine water without life," says Nealson, who was on the Mars team at NASA's Jet Propulsion Laboratory before moving to USC.
But nitrogen would be a much clearer signature of life.
"If you found nitrogen in abundance on Mars, you would get extremely excited because it shouldn't be there [if there is no biological activity]," Nealson adds.
The recent discovery that exotic microbes teem in the rocks hundreds of metres beneath the floor of the Pacific Ocean looks set to fuel the controversy over where and when life began. And it will also considerably boost hopes for life on Mars.
Another key factor in the reappraisal of Mars is the discovery that life on Earth extends deep into the crust. The new results by Prof Stephen Giovannoni and colleagues at Oregon State University, Corvallis, confirm the existence of a pervasive hidden biosphere that may be kilometres deep.
This subterranean life thrives without sunlight, exploiting dissolved gases and fluids percolating up from the torrid depths. The primary producers are microbes that can convert inorganic substances directly into living material using chemical energy alone.
The significance of this discovery for Mars is that, though the surface is hostile to life, the warmer subsurface may be more congenial. Miles down, liquid water aquifers might harbour hardy organisms of the sort found beneath the sea bed in the Pacific. And even if Mars is dead today, life could have clung on underground for billions of years.

Just because we know of how things here on earth react, doesn't mean that that's how everything in the universe acts...
Lichens can survive unprotected in the harsh conditions of space, a European Space Agency experiment discovers.
In an experiment led by Leopoldo Sancho from the Complutense University of Madrid, two species of lichen – Rhizocarpon geographicum and Xanthoria elegans – were sealed in a capsule and launched on a Russian Soyuz rocket on 31 May 2005.
Once in Earth orbit, the lid of the container opened and the samples were exposed to the space environment for nearly 15 days before the lid resealed and the capsule returned to Earth. The lichens were subjected to the vacuum of space and to temperatures ranging from -20°C on the night side of the Earth, to 20°C on the sunlit side. They were also exposed to glaring ultraviolet radiation of the Sun.
“To our big surprise, everything went fine after the flight,” says Rene Demets, ESA’s project scientist for the Foton project. “The lichens were in exactly the same shape as before flight.”

How can you be so sure? Just because we know of how things here on earth react, doesn't mean that that's how everything in the universe acts. There is backround radiation EVERYWHERE in space. What if there is some creature that can absorb this radiation, and convert it into matter, and then using that as an effective way to propel itself by ejecting this matter.
