Many unclassified documents NASA had about the aliens, why would they send encrypted messages using high radio coverage outside the earth, that means they have some stuff that we didn't know in the first place. If aliens are willing to reveal themselves in front of an apes, what would be the reasons? we didn't know maybe aliens are just observing us via higher dimension that the human cant perceive.
>It's like we are observing how the behaviors of monkeys relate to us. 
The same thing aliens observing human how it relates to them.
