Colorful UFO Moves At Different Speeds and Altitudes Over Northern Chile

A group of young people spotted a colorful UFO and recorded its strange activity on video in La Serena City, northern Chile.
The video was recorded in a popular tourist destination at the La Serena beachfront promenade La Avenida del Mar. The recorded video was reported by a Chilean news site describing the unidentified flying object as a small yellow light travelling across the sky at different speeds and at different altitudes.
The video shows the UFO quickly changing altitude. UFO Digest further reported that the voice of one of the witnesses can be heard saying the UFO lands in a bare lot on the beach and ascends again after.
The mysterious aerial object demonstrates several color changes as it moves across the horizon. It flies directly over the witnesses’ heads.
Experts in video editing confirm that the video is real and not edited to change the depiction of the object. However, no one could confirm if the UFO is extraterrestrial or terrestrial. Some commenters believe that the area has been visited or monitored by aliens for some unknown reasons.
Meanwhile, skeptics say that the UFO has a very terrestrial identification. These people point out that the movement and colored lights of the unknown aerial object are consistent with a remote-controlled craft, like a modern quadcopter.
One of the commenters say that indeed aliens are ignoring humans and they just fly over for whatever reasons. Perhaps, they consider humans harmless in a sense these aliens are too advanced for them to care about mankind.
