The Schultze-Makuch team has sadly understated the problem. The
methods that we have to detect life won't even work on most of the
microbes on earth, let alone exotic creatures (like the peroxide
microbes). Detecting small concentrations of microbes is a key part of
many problems, few of which have been found. The molecules of life are
too complicated to identify by a simple and reliable test. The
background environment is too complex, even in the most barren places
on earth, to allow easy extraction of a biological sample. Biodetection
is such a complex field, if not a quagmire. False alarms and low
senstivity plague currently available biodetectors, even in a "known"
environment. However, false alarms are the worst possibility. This is
true even if the extraterrestrial life is mundane from an earth
standpoint. If it is exotic from an earth standpoint, biodetection will ...
