If I was an alien.... tuning into our planet on my alien tablet. The most interesting that i would see would probably be the homo sapiens. Also, the most significant... changing manipulating the other creatures and earth. Thinking about and questioning if aliens like me exist.
If one of my alien nuggas said.. "what if the humans weren't there" I'd most likely respond,

foh, nobody would pay attention to that fukk ass iron oxygen ball without the humans.... what would be the point in that???? To see a bunch of creatures following habits n instinct so they can eat each other..
My aliens homie would respond w some bullshyt about, thats basically what humans do on a higher level,
I wouldn't even bother w that nikka any more
