A bizarre piece of footage has emerged on Google Earth sending conspiracy theorists into a frenzy online.

In the clip which has been uploaded to YouTube, coordinates of a location have been typed into the mapping system to bring up East Lake George in New York state, USA.

The street view angles about until it zooms in on a strange dark shape in the blue sky, reports the Mirror.

The object is difficult to make out but appears to be a dark black shape suspended in the air - or just a smudge on the camera lense.

The account which uploaded the footage is called UFOmania - The truth is out there. Since the clip was uploaded a day ago, it has gained more than 23,000 views online.

And the footage has attracted plenty of comments, too. One viewer wrote: ‘We need to keep an open mind.’

Another added: ‘Everyone knows UFOs are a fact and not a maybe.’ A third said: ‘An excellent find, this is pretty cool work.’

However, some who found the clip were far more cynical. One commenter added: ‘It’s a water droplet.’

‘The coordinates don’t take you some where else. When you look around there is nothing there.’

A third wrote: ‘Not very convincing Kind of looks like it’s out of place like it was photoshopped into me but I’m not an expert.’
