I don't agree with this at all. I can't even figure out what your position is though - you follow up suggesting I'm the one being egotistical? That's deeply ironic... it feels like you may have missed the point I was making. I don't support going around the universe and blowing up barren planets like Mars either, although I would be in favor of bringing new life to barren worlds. I can easily conceive there are other kinds of intelligent life, both on our planet and off of it; and whether or not humans will ever even meet or know of those species, it is still tragic for them to die off.
