UFO sightings that makes us believe that aliens exist.

We all have heard of UFO's. Many people in the world have claimed to see UFO's multiple times. Here are some UFO sightings that makes us think, that maybe aliens are visiting our world.

1. The Stephenville Sightings, 2008

The small town of Stephenville, Texas, 100 miles southwest of Dallas, is mostly known for its dairy farms, but in the evening of January 8, 2008, dozens of its residents viewed something unique in the sky. Citizens reported seeing white lights above Highway 67, first in a single horizontal arc and then in vertical parallel lines. Local pilot Steve Allen estimated that the strobe lights “spanned about a mile long and a half mile wide,” traveling about 3,000 miles per hour. No sound was reported.

Witnesses believed the event was reminiscent of the Phoenix Lights sightings of 1997. While the U.S. Air Force revealed weeks later that F-16s were flying in the Brownwood Military Operating Areas (just southwest of Stephenville), many townspeople didn’t buy that explanation, believing that what they saw was too technologically advanced, for current human abilities.

2. Lubbock Lights, 1951

On the evening of August 25, 1951, three science professors from Texas Tech were enjoying an evening outdoors in Lubbock, when they looked up and saw a semicircle of lights flying above them, at a high speed. Over the next few days, dozens of reports flooded in from across town—Texas Tech freshman Carl Hart Jr., even snapped photos of the so-called Lubbock Lights phenomenon, which were published in newspapers across the country and LIFE magazine.

Project Blue Book, which led the Air Force inquiries into UFOs, investigated the events, and its official conclusion was that the lights were birds reflecting the luminescence from Lubbock’s new street lamps. Many people who saw the lights, however, refuse to accept this explanation, arguing that the lights were flying too fast.

3. The Belgium Wave, 1989 to 90

At the end of November 1989, citizens of Belgium reported seeing a large, triangular UFO hovering in the sky. But beyond the visual sightings, no evidence was found of any UFO’s existence.

A few months later, in March 1990, new sightings of multiple objects were reported, confirmed by two military ground radar stations. Two F-16 fighter jets were sent out to investigate the anomalies, and though the pilots could not see anything visually, they were able to lock onto their targets with radar. But the UFOs moved so fast that the pilots ended up losing them.

Some 13,500 people are estimated to have witnessed the incident, making it one of the most widely experienced UFO sightings of the modern era. The Belgian Air Force had no logical explanation for the activity, but it acknowledged that an unknown activity had taken place in the air. The Belgians reached out to the UK’s Ministry of Defence to investigate further, but once they determined, that the incident was not a hostile or aggressive one, they stopped the investigation.

4. The Lights Above the New Jersey Turnpike, 2001

It takes a lot for motorists to stop alongside a highway to look toward the sky, but on July 14, 2001, drivers on the New Jersey Turnpike did just that. For around 15 minutes just after midnight, they marveled at the sight of strange orange-and-yellow lights in a V formation over the Arthur Kill Waterway between Staten Island, New York, and Carteret, New Jersey. Carteret Police Department’s Lt. Daniel Tarrant was one of the witnesses, as well as other metro-area residents from the Throgs Neck Bridge on Long Island, and Fort Lee, New Jersey near the George Washington Bridge.

Air-traffic controllers initially denied that any airplanes, military jets or space flights could have caused the mysterious lights, but a group known as the New York Strange Phenomena Investigators (NY-SPI) claimed to receive FAA radar data that corroborated the UFO sightings from that night.

5. Roswell, 1947

It’s the mother of all UFO sightings, but no object was actually observed flying in the Roswell incident. In the summer of 1947, rancher William “Mac” Brazel discovered mysterious debris in one of his New Mexico pastures, including metallic rods, chunks of plastic and unusual, papery scraps. After Brazel reported the wreckage, soldiers from nearby Roswell Army Air Force Base came to retrieve the materials. News headlines claimed that a “flying saucer” crashed in Roswell, but military officials said it was only a downed weather balloon.

Ever since, conspiracy theorists have been hard at work trying to prove the wreckage was extraterrestrial, with one man, Ray Santilli, going so far as to release a video in 1995 of an alien "dissection" purported to have taken place after the incident. (Santilli would admit in 2006 that it was a staged film, but he maintained that it was based on actual footage.)

As it turns out, the government was indeed covering something up—but it wasn’t aliens. The crashed weather balloon was, in fact, part of a top-secret military endeavor called Project Mogul, which launched high-altitude balloons carrying equipment used to detect Soviet nuclear tests. The Air Force provided plenty of proof in a 231-page report released in 1997 called “Case Closed: Final Report on the Roswell Crash.” Though the mystery has been thoroughly debunked, interest in the case has only grown, and Roswell’s tourism is heavily based around its famous so-called UFO sighting. The town is home to the International UFO Museum and Research Center, a spaceship-shaped McDonald’s and an annual UFO festival, held each summer.
