Earth was more charming for aliens when dinosaurs existed, suggests study

<p>Social media went abuzz over reports of so-called 'aliens' after claims&nbsp;that a family in the United States saw 10-foot aliens in their backyard. The family's home is in Las Vegas, Nevada and there have been several claims of mysterious encounters in that particular area.&nbsp;</p>

<p>On April 30, two Las Vegas residents claimed that they saw an object falling from the sky. After that, some mysterious figures allegedly emerged from the dark.&nbsp;</p>

<p>After the claims, police have begun surveillance by installing high-tech cameras outside the home of the residents.&nbsp;</p>

<p>Doug Poppa, a former police officer, has been following the story of the mysterious object falling from the sky.&nbsp;</p>

<p>A report by Daily Mail mentioned that it was surprising for Poppa that the Las Vegas Metro Police Department actually placed surveillance cameras outside.&nbsp;</p>

<p>The media outlet mentioned that Poppa interviewed the family who made the call. They told him that the cops installed the camera to "protect" them from UFO fanatics.&nbsp;</p>

<p>It is being reported that Poppa, who is a podcaster, remained unsure about the whole incident, but he also stated that the family is somewhat credible.&nbsp;</p>

<p>Taking to his Twitter handle, Poppa wrote: "THE VIDEO CAMERA SURVEILLANCE SYSTEM WITH THE WIRELESS TRANSMISSION LINK THAT I RECORDED AT THE HOME ON MAY 19, MUST HAVE BEEN A MIRAGE OR A FIGMENT OF MY IMAGINATION IF THE LAS VEGAS METRO POLICE ARE TO BE BELIEVED." &nbsp;</p>
