Easier to read:

Nordics: Bear the most similar resemblance to humans
Grays: Believed to be small, massive-eyed, hairless creatures and are the most common
Amphibian type: Lizard-like creatures with scales and a long tail, and often walk on two legs
Insectoids: Resemble a praying mantis and are bug-like beings. Rarely seen but appear as being "in charge"

Sounds like TV cartoon instead of being reported as "news".
