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

Our planet may harbor 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.

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.

The descendants of this “second genesis” may have survived until today in a “shadow biosphere” which is beyond our radar because its inhabitants have biochemistry so different from our own.

Holy crap!  That explains it perfectly!

I know explains what?

The broad that wants the world’s largest boobs, 34KKK…..or PETA……or that Jolie look-alike that squirted out 8 puupies with no job and wants donations to help pay for them to live……they are all alien life forms.
