Alien Abduction Entities

The alien beings who are known to abduct humans in order to perform forced medical examinations (particularly revolving around the human reproductive system) have been widely reported since the 1950s, even though previous abductions from the late 1800s and the beginning of the 1900s are acknowledged as the earliest abduction stories. Some ufologists theorize though that alien abductions are even older but are misconstrued as encounters with gods or angels or even mythical beasts seen in ancient mythology of many cultures around the globe. Even though these abductions span time and geography, several common elements tend to always emerge. The abductees who survive these encounters have been shown to have the emotional impact close to that of post traumatic stress seen in former combat soldiers, those who have been sexually abused, and people who have undergone physical and mental torture. The types of aliens who carry out these abductions seem to fall in particular types of categories, showing several definite alien species who visit Earth.
