Long story short, we found irrefutable evidence of an advanced humanoid species living under our Oceans. Using the Multibeam sonar, we found their dwelling areas, and also what appear to be underwater vehicles of some kind. The creatures themselves were tracked by the Navy over the course of 2 weeks, using a submersible equipped with special deep-sea observation equipment.

The creatures displayed speeds of 70+ knots… faster than the sailfish, which is widely considered to be the fastest creature in the ocean. They also were recorded emitting sounds that resemble marine communications, and instruments also captured the emissions of “precision sonar blasts” that damaged the hull of the submersible, according to the Navy report. There is footage of the creatures, including juveniles.

They look nothing like any fictional depiction out there. They do not have a fish tail, they are completely humanoid, but *extremely thin/tall*. Their bodies were covered in a material resembling elemental mercury, that looked like it was ‘moving’. We observed at max 5 of them at once. Varying sizes, but otherwise identical in appearance. Their eyes were completely white, and there was no visible hair, nor any features that implied male/female. No visible ears, and the mouths were wide, and lipless.

The Navy confiscated most of the hard evidence, all we have are some sonar readings, that are only anamolous if you know what you are looking for. We are not alone, but they aren’t from power space. In order to exist at these depths, and under astronomical pressures, these beings are either invincible, or they have evolved so far beyond us, that they have some kind of technology that negates both of those dangers.
