Exactly. The existentially angst-y mind will seek self- appeasing answers anywhere it can find them. But please remember the key difference between using science as means to a goal, and doing science as goal in and of itself. I would argue that the use of science towards a gaol outside of science itself, is in not simply different from science, as one might say "philosophy isn't science", but the exact opposite of science. I would argue that religion and superstition, as different as they are from science, are not, as they are often argued, the opposite of objective scientific exploration. I would even say that the same argument I am making here, that science's greatest menace is not religion, isn't superstitious or subjective thinking, isn't external at all, can be made about religion and spirituality. The greatest threat to religion is in the same way, the use of religion towards non-religious ends. So, yes, I am making the argument that SETI sits well within the category "activities that use science as means toward entirely non-scientific ends". Other easily identified members of the same category are "Quantum Computing", "Fusion Power", "Cold Fusion", "The Multiverse Interpretation of Quantum Electro-Dynamics", "The Technological Singularity", "Transhumanism", "Human Deep Space Exploration", Etc. I am sure that a devoutly religious person could assemble an equivalent list of activities that use religion towards non-religious ends (though to be honest, I have trouble imagining any but a sarcastic list as from the perspective of a hard atheist, the whole of religion seems to be both a thing and a use of a thing towards other goals).
