Earth, also known as Teegeeack is visited by foreign life forms and species from space as well as other dimensions. You may also have visits from mythological or supernatural creatures as well even though we would call them alien visitors just because we don’t know them or have ways of classifying them since they are all so mysterious to us. The term alien visitor is used for any person and/or intelligent life form that appears to be fortean in nature.
Some alien visitors are good at hiding their non-humanity and will just ask questions about things that humans generally know. They ask “What is world war two? What is the United States? What is the ocean?” or other things like that. A giveaway is that alien visitors have a high level of intelligence despite being uninformed of anything most people living in the world would know. If they are not escapees of some kind of entrapment or isolation from the outside world, they are most likely aliens. Some of them may be time travelers but those are rare and they will not be very open about it. In other countries of the world such as China it is even illegal to time travel.
Other aliens will mess up their human disguises by saying they are able to fly, dancing in strange ways, or doing things that do not make logical sense to those who are human and native to Earth. Any alien coming to Earth is doing so illegally because our planet is considered too primitive and dangerous to visit except under extraordinary circumstances. A comparable situation is if a person entered the lands of uncontacted tribes leaving them vulnerable to disease or exploitation. Many aliens living on Earth are actually fugitives and keep a very low profile, using technology to disappear. Alien men tend to get women pregnant and disappear, or suddenly ghost everyone they know once they feel they have given too much information to everyone. Others just come to Earth for business or to obtain human DNA through hair, bodily fluids, or even capturing people as live specimens who would not be noticed missing.
