The explosion of SpaceX’s Falcon 9 rocket on Sept. 1 was apparently caused by an alien spaceship, according to alien enthusiasts. The video of the alleged UFO can be seen in slow motion on YouTube, which has since been viewed more than 700,000 times.

As seen in the video, a dark object moves toward the SpaceX rocket while it is still on the platform. Suddenly, the rocket explodes.

As expected, many theorized that the object was of alien origin. Some have even suggested that the object was a drone attack.

However, others dismissed the object as simply a bird. Nevertheless, UFO hunters are adamant that aliens caused the explosion.

“If between the left tower and the right tower there is at least a quarter mile, and the so-called bug beamed from one end to the other in 1/4 second, then that bug is at least going 3,600mph minimum,” says an alien enthusiast, Sputnik News reports. “It’s not a bird. It’s an alien with a laser that destroyed the rocket. You can tell it is not a bird or a bug. Look at how the left tower hides the UFO behind it when you slow it down near the top. This indicates the UFO is behind the tower, not in front of the camera lens dropping the possibility of a bug.”

On the other hand, the company has not released details about the incident yet. Overall, experts estimate that the payload was worth around £150 million or $200 million, while the rocket cost about £45 million or $60 million.

Another alleged UFO was also filmed flying over a remote village near Kuala Krai in Malaysia. While alien hunters believe that the object was actually a spaceship of alien origin, the local authorities say that this was most likely fake as they have not received any report from onlookers about the incident.
