Greys are humans, but they're placed one dimension down from us. I don't have a good way of explaining it, you have to find a way to "see" it yourself, but I'll post these I made in discussing it with someone before. Pics here are a basic structure of importance.
Greys are "backwards" compared to us, thinking per default outward and being unable to see any other way of doing it. So to connect to their cloud from our view, the connection has to reflect around a corner so to speak. Was it straight, they would stop being greys, and their standard of life would become difficult and harsh like our.
