In case anyone is curious, I should probably explain how I know this is the cause of alien lifeforms. You see, before I had exited the building through which I had entered into this Testing Area, as I shall refer to it from now on, I believe I saw one of these E.T.s. It seemed to wish to blend in to our culture by wearing a man's suit, so as not to cause alarm, but it could not hide one very obvious feature, the lack of any facial features. I theorize that perhaps it contains all of its perceptual body parts within its head, and perhaps that it feeds through some sort of filter method. At any rate, despite its lack of eyes, it seemed to be staring at me through a window. At first I thought I had just not seen clearly as I walked by, but now I know better. I have not seen the creature since, but I believe it was the alien that sent me to this Testing Area. I am still trying to find my way through this tunnel.
