Apparently, Hawaii is not only conducive to Mars simulation because alien hunters say, an alien base could also be hiding on one of the mountains in the Pacific.

Recently, UFO hunters claim that an alien face appeared on ash clouds coming from a mountain in Mexico. Instead of stopping there, some even suggested further that this is a sign that an alien base is being built inside of the mountains.

Meanwhile in Hawaii, UFO hunters said they spotted a flying saucer above a potential alien hidden base. The alleged alien UFO base was identified when a flying saucer was seen hovering in the mountainous range near the Kaneohe Bay, according to a report. This incident alone garnered the interest of many UFO hunters and alien enthusiasts. Many of them believe that extraterrestrial already arrived on Earth and that they do have access to the planet. The recent sighting they say is proof that the intelligent out-of-this-world beings are establishing hidden bases on the planet.

Some witnesses even sent photograph's as 'evidence' to the Mutual UFO Network; some even claim that UFO hunting was not their intent but the flying saucer accidentally revealed itself and was captured on the images, according to Health Aim.

For years, conspiracy theorists believe that Hawaii is an alien hotspot, although there are no concrete evidence yet to prove the claim. But reports say that this is due to the mountainous terrain in Hawaii that makes it easier for alien life forms to hide from plain view.

Meanwhile, in Mexico, a gas cloud emanating from a volcano purportedly showed an alien face looking upward in the sky with a visible eye and mouth. While this may seem just a coincidence, some argue that this is some sort of a sign or a signal that another alien base is being built in Mexico.

The alien face appeared above Popocatépetl, the most active volcano in Mexico. And although it can be a simple cloud formation, alien hunter Scott Waring believes it is something else. "This is not randomness, this is the deep thought of an alien in the base 4km below this volcano. We have observed and recorded hundreds of UFOs coming from the mouth of this volcano," alien hunter Scott C. Waring said in a statement.

Amidst all the intriguing alien conspiracy theories, a former NASA employee insists that it is very unlike that these mysterious objects are works of extraterrestrials. It might just be a simple unfamiliar event that the mind struggles to understand.

"Our sensory system is functioning absolutely perfectly for Earth conditions," says James Oberg, former NASA employee in an interview with Atlas Obscura. "But we're still a local civilization. Moving beyond our neighborhood has been visually confusing," Oberg added.
