Recorded evidence of non-human intelligent beings
This article gives an overview of alleged media evidence of NHIB, such as photos and videos. Witness testimony is, as in most things, the most voluminous but probably least convincing kind of evidence. A major aspect of convincingness might be the perceived difficulty of faking the evidence, so supposed indicia of reliability such as the consistency of the testimony over multiple questionings have an impact on the perceived reliability of the evidence in cases of testimony. For purposes of this article, recordings of people's testimony, whether self-written, in interviews, or otherwise, is not considered media evidence. On the other hand, alleged handwritten notes from NHIBs, or something like that, might be considered media evidence or NHIB artifact. Just as media evidence can include printouts and digital files of photos and videos, it can include printouts or digital files of things like medical imaging scans of alleged NHIB corpses.
Videos of alleged living NHIBs
There have been a handful of videos allegedly showing real live NHIBs in the flesh.
Videos of alleged dead NHIBs
This includes several alleged alien autopsy videos. Note: Jonathan Reed's video of Freddy is in the list of living alien videos because Freddy was allegedly alive but not moving much.
Audio recordings of NHIBs
A few recordings of alleged NHIBs speaking English have been disseminated. The alleged Ashtar Command transmission in the 1970s; Thor Han Eredyon was allegedly heard saying "yes" in a video recorded session with Elena Danaan where she asked him questions and he answered speaking through her alleged implant, in response to a question about whether he listened to music; Jonathan Reed's alien was recorded screaming a bit of which was played in one of the Art Bell interviews he did.
Medical imaging of NHIBs
They allegedly scanned some of the possibly-alive, possibly dead aliens from the Varginha UFO incident in a medical imaging machine, but it's not clear whether any resulting images were disseminated.
Several of the alleged Nazca mummies have been scanned in CT and/or MRI machines and the images have been published and extensively discussed.
Biological molecular evidence
It is not known whether any alleged nucleic acid sequencing or other data straight from an analysis machine has ever been published.
DNA sequencing
Jonathan Reed claimed a biologist he had given tissue samples to had biological DNA evidence on the nature of Freddy (NHIB) although the biologist was allegedly murdered prior to publishing the evidence.
The molecular biologist leaker said that the grey-like beings whose cells they were analyzing had "tripalindromic regions" in their DNA that their team speculated was for "exobiospheric" genetic engineers to use as recognition sequences (i.e. "handles" for manipulation).
Proteomic analysis
The molecular biologist leaker said that they were trying to determine the "genome and proteome basis" of a cultured cell line derived from epithelial cells of grey-like beings.
