Over the years there have been many alien sitings. Some of them have been outragelously  peculiar. However, there have been similar details in most reports. Many say that they have woken up from deep sleeps with markings in the shape of a hexagon with an HF inside of them on different parts of their bodies. For male cildren and teens, it is typically on their foreheads or above their bellybutton. For female children and teen, it is most likely going to be on their palms. Although, male adults have not had any markings that we know of. Female adults usually have had them on their bottom left heel or their right shoulder. As far as dissapearances have gone, there have been no dissapearance attributed to this species. We believe most aliens to be peaceful, however, there have been some reports of life altering changes in most males marked with a sign on their foreheads. In more gruesome cases, males have either suffered from amnesia or have had certain parts of bodies shrunk. You might ask, how can I protect myself from these side effects. To prevent amnesia we have figured out that when walking, you should take one step back for every three steps forward.  For preventing the shrinkage of body parts, we've found that drinking a mixture of prune juice and milk twice a day for one week is the best way insure that all body parts stay a normal size. P.S. We can't believe that you actually believed us. Happy alien huntings!
