This could also perhaps mean our understanding of life in other planets is more dependant on not its composition but just its physical conditions which influence the development of life. What they coudnt understand, they attached their stories interlinked with culture and religion to it. Now science with the intersection of astronomy,biochemistry and cosmo-chemistry has provided basis for questioning the origins of life in the universe on a larger foundation of knowledge.
Life is tenacious, and it completely permeates the surface layer of the planet.
We find life beneath the deepest ocean, on the highest mountain, in the driest desert and the coldest glacier, and deep down in the crustal rocks and sediments. A far away world from the anthropic principle.
