They are being examined by GOVERNMENT AGENTS -----A lot more logical than actual ALIENS, and we know SOMETHING REAL is being done to them, as the reports are too consistent to be simply "made up" AND the Government is the only entity capable of pulling off something at such a large scale.-----------That leaves the question why? Also simple enough to deduce, There was likely an accident (or unethical weapons test) involving toxic, radioactive or biological elements that resulted in many people being exposed.---To avoid public panic or scandal, the operation is being kept SECRET.-------A" stroke of genius" was to have an "alien dummy" or "animatronic" present so people will assume "aliens" should the amnesia drugs wear off.---That would make them reluctant to talk about it. or if they did, not be believed. The "Flaw" in this set-up, however, is that the same dummy was used. The victims describe the SAME "Alien"---which lends an air of TRUTH to their reports, otherwise there would as many different accounts as there are witnesses if they were made up.---This opens the situation to deductive reasoning with results as above. SO, In MY opinion it is a government project to cover up exposure of many people to a hazardous substance and track them. They shoulda used several different alien models so the consistency would not have been so obvious and open their secret to deduction.
