It has thick atmosphere that could help protect us from space radiation. it is do dense that we could actually attach wings to our arms and fly on the Titan. It seems that Titan contain a global ocean beneath it’s ice shell according to some scientist’s there is microbial life present underneath this ocean. Scientist surmise that the atmosphere of early Earth was similar in composition to the current atmosphere on Titan, with the important exception of a lack of water vapour on Titan. New research provides a evidence of rainfall on the north pole. It has been speculated that life could exist in the lakes of liquid methane on Titan, just as organisms on Earth live in water. Such organisms would inhale H2 in place of O2, metabolize it with acetylene instead of glucose, and exhale methane instead of carbon dioxide. However, such hypothetical organisms would be required to metabolize at a deep freeze temperature of −179 °C.
