A Guide To The Top 5 Alien Types

There may be two types of people in this World, those that believe in Aliens and those who don't but for those who have seen them there are five basic types,  The Greys, The Nordics, Tall Whites, Reptilians and Insectoids.  
Astrophysicist, Dr. Eric Davis, has collated what people claim say they saw and The Greys is the most common, short humanoids with grey skin and large black eyes and apparently are not shy about inserting probes in places where probes should not be inserted unless by a medical professional.
The second most common are the Nordics who are described as tall and almost human in appearance with blue-eyes and blonde hair and can communicate with us  telepathically unlike the third most 'seen' alien who are the Tall Whites who stand over six feet tall with pale white skin, bald heads, and light blue or green eyes.
Less common are the Reptilians who are said to be humanoid creatures that stand upright, but have reptile-like skin asnd the fifth most sighted alien which is the Insectoids who look a bit like praying mantises, if praying mantises could stand and were about six to nine feet tall and wear robes and jewels as well.
There you go then but it is all obviously very useless if you are being pursued by a Grey skinned alien waving a probe around it's head or a walking praying mantis in a robe but no need to make them even more angry by getting their classification wrong, that's just poor manners.
