There is a 3-million-year-old Gigantic Underground Cave in Vietnam linked to mysterious sightings of strange reptilian and gray creatures that stand on two legs.

Hang Son Doong, which translates as “mountain river cave,” belongs to the Phong Nha-Ke Bang grotto system in central Quang Binh Province, Vietnam.

It was discovered accidentally by a local man named Ho Khanh in 1990 while visiting the jungles in central Vietnam. It is more than 200 meters wide, 150 meters high, and at least 6.5 kilometers long. An entire New York city block can fit inside.

This three million years old subterranean realm has grasped the attention of the ancient astronaut theorists.

According to local residents, the most notable about Son Doong Cave are the strange creatures that are believed to dwell within it.

They describe seeing reptilian-type humanoid beings emerging from the Son Doong cave, and they believe that they actually live deep inside this cave.

Interestingly, these reptilian-type humanoid beings are similar to the seraphim, or the winged serpents in the Kabbalistic tradition. The seraphim are said to have g one and lived in the inner Earth, according to Kabbalistic teaching.

This underground world has been rumored to exist by U.S. soldiers who told tales of seeing horrific, lizard men emerge from it during the Vietnam conflict.
