First of all, humans are not what humans think they are. Humans have erroneous conceptions as well as gaps of knowledge of what they are. Humans will literally make up reasons why they did something. You can see this clearly with people with severed brain connections. But it's true for everyone. You just don't see it clearly because you're not smart enough and you don't have enough information. Humans are largely programmed, you can see this by getting familiar with several cultures. Countries have different ways of doing things and those things are very much instilled in people, making them act in certain ways. In fact, aliens would probably be able to predict almost everything you ever do. I see the patterns of younger people. It's all repeating. Imagine seeing humanity over many generations. Humanity would be almost like a plant to aliens. Like a collective of all. Sometimes withering, sometimes diseased. Slowly growing.
Just another plant (planet) out of many they can visit at will. Some bear fruits. Information is what programs you. Hence it's not given to you.
