UFOs

I'm very skeptical as well, but most of these comments are the worst. Zero effort Reddit-type posts that contribute nothing.

Here are two live translation comments of the same testimony from r/ufos:

The anatomy portion was spoken in a personal capacity by Dr. Jose Salce Benitez who had 30 years in the Mexican Navy, currently the director of the Navy's Scientific Health Institute and was at one point the director of the Navy's Medical Forensic Service.

• Bodies covered in a diatomic white powder that granted desiccation for extreme natural preservation, was carbon14 dated to: very fkn old (around 1000y)
• Tridactyl (3 fingers 3 toes) no carpals or tarsals with fingers going straight to armbones. I had a hard time with some specifics around here but they cannot grip thumb-wise and as such have to wrap their fingies around objects
• Circular, complete and continuous ribs, having around 14
• Deep/concave cervical spine (neckbones) with other features hinting that the head is retractable similar to turtles
• Strong but very light bone structure much like a bird
• Pneumatized (air/gas formed) cranial cavity, making a large space for oversized brain matter
• Orthopedic implants perfectly fused with skin and bone, composed of what we consider metals for spacing structures and equipment such as cadmium & osmium
• Ocular orbits very broad granting wide field of vision
• A jaw joint, but no teeth. They could swallow foods but not chew
• Spine connects to the center of cranial floor, a rarity that does not occur in primates who have a rear position
• Intact oviducts (fallopian tubes) containing eggs, alleges this is impossible to falsify
• Very broad range of motion in their shoulder joints
• Specimen have intact fingerprints, that are linear and horizontal as opposed to a human's circular prints
• Unique DNA not matching over a million existing sequences. 70% similar to known DNA, 30% unknown. For relevance, lists that humans are less than %5 different to primates and 15% to bacteria meaning the 30% or more the specimen contain is far outside terrestrial parameters

In summary, the bodies are a non-human species presenting irrefutable differences to written biology/ taxonomy of the evolutionary tree with 0 common ancestors or descendants

And a second one, with slightly different details:

Im not very good at Spanish, but the part where the Forensic Science specialist describes the bodies:

• Bodies 60 cm tall covered in a white powder that under electron microscopy are revealed to be a type of common algae (diatom), which preserves the bodies and inhibits bacterial growth, naturally conserving the bodies. Humanoid structure with hands and feet having only three 'fingers'. The bones show signs of wear in the place where you'd expect from motion, and they are tough, but light, like a bird's.
• The head is very large relative to the body. The cranium is likewise tough but lightweight, with a large intracranial cavity which contained a large brain. The eyeholes are very large and would permit great stereoscopic vision. Very short nasal cavities, and a mouth cavity that by its mandibular articulation and complete absence of teeth indicates they ate by drinking and cannot masticate.
• The neck is strangely connected to the center of the skull, which is unusual because in primates the neck is usually joined at the back of the skull. The 4 or 5 cervical vertebrae suggest that the neck was slgihtly retractable, like a tortoise. The beginning of the thorax has joints to the arms similar to a bird's. The ribcages bones are completely continuous and circular and the space between them is small. In the abdomen we can see the presence of three eggs, and in the abdominal cavity, using tomography we can see at the milimetric level that there exist oviducts containing milimetric eggs, suggesting this creature was in a process of constant gestation. This is further proof they are biological and organical, as their method of reproduction including the milimetric eggs in the oviducts would be impossible to fake.
• We can also observe through tomography the muscles, ligaments, blood vessels and organs and organelles that are yet to be defined in future studies. There is complete harmony in the wear down near all the joints, consistent with their biomechanical locomotion that ends in fingers that have 5 falanges used to grab and manipulate objects (since they have no thumbs). They dont have carpal or tarsus bones, the falanges connect directly to the arm and forearm bones. They find microscopic bubbles(?) in the fingers which they clame are impossible to fake. He makes a comment on them having a square something I cannot translate, being weird as most animals on this planet have them round or circular.
• Some of the bodies have metallic implants perfectly lodged into their bodies and up to the skin, fused with it. The metals are several combinations of which the worthy mentions are osmium and cadmium (osmium is the rarest precious metal on Earth and the Universe, we use it in satellite communication).
• The DNA results were compared with over 1000000 known species, and the results show that on one of them, 70% of its genetic material matches known sequences, leaving a difference of unidentified 30%. This is relevant because humans relative to primates have less than 5% difference, and have less than 15% when compared to bacteria. The results are published online, free for anyone to research. Maybe users more experienced in Spanish can translate the part they mention after describing the fingers, I did what I could.
