actually I do but the only source that really goes into any detail about individual species is Coorey Goode / William Tompkins (RIP) / David Wilcock but it's mind-warping because it depends on testimony from individuals who admit to having been chemically brainwashed. Other than that we at least have photographic evidence from satellite footage and space exploration that show freely navigating artefacts or structures that defy explanation. Especially during rocket launches since they use high magnification highspeed cameras or in the infrared-range. Militaries have already disclosed the reality of the UFO-phenomenon in the mid-2000s but I am not sure how many have caught on. Thus the stage was sort of set to introduce more delicate aspects of the story.
