I briefly consider the impact of recent developments in astrobiology, planetary sciences and philosophy on our changing historical perspective of extraterrestrial life and intelligence. In particular, I focus upon the re-emergence of catastrophism in Earth and planetary sciences, which is no more -- in sharp distinction to the historical experience of 19th and the first half of 20th century -- associated with the terrestrial exclusivist and the belief in uniqueness of human intelligence. On the contrary, several recent astrobiological hypotheses emphasize the complete inversion of this perspective in looking at global catastrophic mechanisms as keys for understanding biological evolution on the widest spatial and temporal scales of the Milky Way. Shifting perspectives of the physical preconditions for the emergence of life and intelligence and reducing the controversial "fine tuning" of the universe for life to a set of observation-selection effects has significantly contributed to the development of this set of ideas.
