I believe they were terms introduced by clemvidal in his recently released PHD thesis (pg. 204). -- I think we have enough data to be confident that life has arisen elsewhere. I tried to explain my reasoning in the post. Of course, you are entitled to your perspective and it is a fair one to hold. We have no empirical evidence to the contrary. In regards to your points 1-4 I don't necessary disagree with any of your statements. My point with the article was t state that it is highly improbable that humans are the only intelligent species to ever emerge in our universe. That's all. I think its probable that intelligence has emerged several times, although I don't think anyone can assert with any degree of scientific accuracy how many times we should expect it to have arisen.I don't know if "universecentrism" is a word outside of this post.
Steven J. Dick (2000, 196) summarized stages in cosmological worldview
development from Geocentrism, Heliocentrism, Galactocentrism to Biocentrism12. We
add two worldview stages, Intellicentrism and Universecentrism. Three “centrisms”
have been refuted scientifically: Geocentrism, Heliocentrism and Galactocentrism.
a statement we don't really have enough data to assert yet, I think.
