The DNA of the bizarre 'alien baby' cannot be identified, despite four labs using the latest methods - will the mystery ever be solved?

For UFO hunter and leading researcher Jaime Maussan (56), the news is further evidence that the strange creature does not come from our planet.

The curious being, found in a ditch in a farm in Mexico in May 2007, is the most puzzling find of his life.

“At the start I thought it was a bad joke, perhaps a skinned monkey,” he told BILD.

Only when the man who found the creature died in strange circumstances did he manage to convince his widow to let him carry out tests.

“We took samples of tissue, bone, hair and skin and sent it to be tested.” But the three labs in Mexico and one in Canada did not know what to make of it.

“They claimed the samples had decayed too much to produce coherent DNA,” he said

But tests on the creature’s cells showed it was not known to exist on Earth, and it had a thin layer of skin covering the small body.

Its eyes, brain and ears were more pronounced than on other primates.

Maussan said: “The lab tests failed, because the DNA is unknown.”

He kept the 'alien baby' in a safe at first: “The tissue dries very quickly and doesn’t decompose.” He is also looking at photos of the creature taken by the farmers before they drowned it which will be released soon.

But where does the being come from? “I want to wait for more tests rather than make a quick judgment, but I don’t think it’s from our planet…”
