Experimenting on this one

Alien K and his team had been observing humans on earth for a long time by now. They had studied animals and the research had been smooth so far but it all had come to a halt when they had run into humans. They had observed humans had a similarity with other creatures, at least with some of them, but then one day Alien K and his team had observed Josh a boy under their investigation eating with a spoon in an empty bowl in front of a camera. Josh was simply angry and was contemplating life but here is what the team wrote about him. 'We observed a strange behaviour yesterday' - wrote Alien T, the secretary of the group. One of the subjects was performing eating like movements in front of a camera and the bowl he was eating from was empty. This contradicts what we know of eating behaviour. Humans and other creatures of earth perform eating like we do fuel ourselves with methane gas in methane stations. It is as if we went to a gas station put on a tube wich was connected to an empty tank and stood there waiting. Why on mars would an alien do that. It is obvious this terrestrial creature was not obtaining fuel, or nutrients like they call them. Yet he stood there for a long time putting the spoon in the empty bowl then putting it into his mouth always looking at the camera while it was filming. These creatures perform these actions often we have noticed. We have observed this pecuilarity only in humans among them.
