A Google timelapse allows users to see the history of Area 51.
A new Google timelapse reveals the fascinating way the facility has evolved and changed since the 1980s.
The feature allows you to see how places across the Earth have changed each year since 1984.
In 1984, Area 51 was largely cut off with few roads and infrastructure.
Into the 1990s, the base gets expands as new buildings and passages are developed.
The original runway was made much bigger and a second one was also added as the base was developed.
They claim Area 51 is a hotbed for UFO sightings and the US government is hiding the true purpose of the secretive land.
It is also suggested that military scientists use recovered alien space ships to reverse engineer them and create their own secret aircrafts.
Earlier this year a source told Express.co.uk that so-called black projects, involving the development of top secret technology does take place inside Area 51.
Although, its existence has been known about for years, the US Government did not officially admit it was there until 2013.
