Alien life 'may exist among us'

Never mind Mars, alien life may be thriving right here on Earth, a major science conference has heard.

Our planet may harbour forms of "weird life" unrelated to life as we know it, according to Professor Paul Davies, a physicist at Arizona State University.

This "shadow life" may be hidden in toxic arsenic lakes or in boiling deep sea hydrothermal vents, he says.

He has called on scientists to launch a "mission to Earth" by trawling hostile environments for signs of bio-activity.

Weird life could even be living among us, in forms which we don't yet recognise, he told the American Association for the Advancement of Science (AAAS) meeting in Chicago.

Cool!

i believe you i believe you..

i dont wanna be the retarded fool who didnt listen and ends up being the first one killed...

ill take them to OUR LEADERRR!!!!!!!

Damn.. Ive been found out...

Nah, but seriously... I wouldn't doubt it.

Think they are plotting a takeover?
Maybe I could jine em, De Devil won't let me in....
'Fraid I'll take over

.... De Katz

so in short, he is saying that deep within earth there are probably organisms that are not from earth but carried in from the big bang or something?

Kinda like from War of the Worlds or that OLD movie Evolution?
Except.. not?

arent we all a product of the big bang anyways? Jeeze who are these science guys?

No I think they're saying life forms might exist on Earth that don't have conventional biology.

"If it exists, weird life could be based on DNA and RNA - but with a slightly different genetic code or different amino acids.

At the other end of the spectrum, we could find creatures which have more drastic differences.

"Maybe one of the elements life uses - carbon, hydrogen, oxygen, nitrogen, phosphorus - could be replaced by something else," said Professor Davies.

"When I say that, everyone immediately thinks of silicon life - because of Star Trek. But I'm not talking about anything that drastic.

"For example, most of the jobs that can be done by phosphorus can be done by arsenic."

Arsenic may be poisonous to humans, but it has chemical properties which might make it ideal in a microbe's machinery, he said."

I heard something about arsenic before. That its only poison to us.

Maybe it was that movie evolution

Life didn't pop up until a couple of billion of years after the big bang at least. the planets were well formed when this occurred.

It's possible life came in from other sources in the form of asteroids and what not,seems somewhat unlikely considering asteroids have a lot less to work with that the earth does composition wise so life probably wouldn't occur on them.

The 'weird life' like germs that hang out in volcanoes and stuff probably evolved on earth, Its super interesting how life can thrive in such vastly different enviroments, but its more likely an example of the awesome power of evolution than aliens.

If it's true it means far more possibilities of life elsewhere in the universe. If life can form with more chemicals than we know about then it could be much more common.

Oh, theres definitely life elsewhere in the universe.
Itd be weird for Earth to have the only life throughout the universe, since the universe is so huge.

UFOS have been reported emerging from the sea for many years!
Those life forms must be more advanced than anything known on Earth! The Shag Harbor event is extremely interesting and worth looking into. In a nutshell it is a case where an UFO dived into the sea,off the coast of Nova Scotia,where it remained for several days and was investigated by the Royal Canadian Navy, And the US Navy! They call these, USOs unknown submerged objects!

Cats are Aliens, look at their alien shaped heads.

OH MAN! thats freaking me out
