The theory that there’s no life beyond Earth because we haven’t found any yet just doesn’t hold water (or methane, as the case may be).
Rachelle Flick of The
Space Reporter explains that Search of Extraterrestrial Intelligence (SETI) astronomers recently told members of the House Science and Technology Committee that “alien life
could be detected within 20 years.”
Senior SETI astronomer Seth Shostak said that this could occur in any of these three ways: life
could be discovered within our solar system; traces of oxygen or methane could be found within the atmosphere of an exoplanet; leaked or deliberate signals that were emitted from other planets could be picked up on.
Shostak added: The fact that we haven’t found anything
[to date] means nothing. We’ve only just
begun to search.
