Okay the summary is that whenever faced with puzzling questions about humanity's past it was because of aliens according to him. Plus his hair is awesome.
Seriously, why does he look like this??? It's like he's doing it on purpose. He can't actually thinks he looks good like this, it's not even like he's expressing his individuality in a creative way, it's just crazy unkempt hair, the sunburned looking skin with white around the eyes and mouth. The only thing I can say good, is that as laughable as he looks, looks do not alone make him uncredible. He could be really smart.
