I asked another skeptic about this, and he also refused to answer my question. Why are you dodging it? Is one allowed to hypothesize, to surmise an ET explanation when no other explanation works? Does the question make you uncomfortable? Do you feel like I'm asking you to commit to the hypothesis? I'm just asking: Can it be on the table? You don't have to agree with it, but can one propose it without being branded a nut?
