American astronomical society, dps meeting #30, #2107) with this new information, it seems very unlikely that stable planetary systems, in which a small earth-like planet resides in the habitable zone, exist in any other galaxy in our universe this does not even consider the other design parameters that are required for life to exist anywhere .

The atmosphere of earth is the layer of gases, 004% carbon dioxide, and small amounts of other gases air also contains a variable amount of water vapor, .

The first point is that almost any gas other than n 2 and co 2 in earth’s atmosphere, however generated, is out of thermodynamic equilibrium because of the earth’s high o 2 levels so, the argument that earth’s atmosphere is out of thermodynamic equilibrium reduces to a statement about the high levels of earth’s atmospheric o 2 . Then the total number of civilizations that have arisen in our galaxy would be closest to _____ a) 10 b) 100,000 get into earth's atmosphere a) it was captured .
