Contradicting yourself? They most likely evolved on a different evolutionary path than ours, so they are going to be different, and are going to have uncomprehensible/unearthly features. Again contradicting yourself. Grays are the most believable type of alien, along with reptilians or 'Dinosauroids': "O RLY?" If you compare them to other types of aliens like Muons (they were supposed to come in 2001), Venusians (well now we know that Venus is uninhabitable), Nordics, MASTER AETHURIUS (don't ask, it's a iwerd contactee story), and Squirrels, you will see what I mean. You saying that 99% they are grey??
