We know (well, not everyone knows this) there are more than 50 Alien species catalogued (57 i think), that have visited earth
and the gov has been dealing with some,
lots of people have encountered them like in an abduction scenario.

Here´s a video showing each race and the location and time of the encounter for more references.

Notice some of them look alike and some look like us but a little different
some could be humans in a different evolutionary state or Hybrids

This is clearly intelligent life from other planets that evolved in other ways than Humans have
this may be because some evolved from reptiles or dolphins or whatever animal instead of chimpanzees like us
and their planet conditions and adaptation process also shaped their morphology
Why some have the black layer on eyes?

and these are humanoids
of course there are non-humanoid aliens
wonder how they look like

it would be good to know the names of each race and maybe symbols so if any1 knows

last one is a Reptilian pretty obvious
and u can see some Greys types and Nordics?

irrational skeptics: this is no joke (less info)
