Purpose.

There's no escaping reason, no denying purpose, for as we both know, without purpose we would not exist. It is purpose that created us, purpose that connects us, purpose that pulls us, that guides us, that drives us; it is purpose that defines us, purpose that binds us. We are here because of you, Mr. Anderson. We're here to take from you what you tried to take from us. Purpose.

Human beings are a disease.

I'd like to share a revelation that I've had during my time here. It came to me when I tried to classify your species and I realized that you're not actually mammals. Every mamal on this planet instinctively develops an equilibrium with the surrounding enviroment. But you humans do not. You move to an area and you multiply and multyply until every natural resource is consumed. The only way you can survive is to spread to another area. There is another organism on this planet thet folows the same pattern. Do you know what it is? A virus. Human beings are a disease. A cancer on this planet.
