A video on YouTube claims that NASA photos of a giant "alien worm" slithering along the Martian surface may be proof there actually is life on Mars.
Can it be true?
The video magnifies a NASA still photo of an unidentified area of the red planet taken as a reconnaissance satellite orbited overhead.
The terrain in the photo is typically Martian, with rocks and boulders strewn across a meteorite-blasted, fairly flat and desolate landscape. Except for the twisting, squirming, wormy object seemingly burrowing into the Martian soil. It's so large, it casts its own gigantic shadow.
A second photo, enhanced, colorized, and from a different angle, seems to show a twirling mass being buffeted by what little atmosphere Mars still has left.
But is it a giant alien worm digging its way?
