We Are Not Alone: Why We Have Already Found Extraterrestrial Life

by Dirk Schulze-Makuch, David Darling

Extraterrestrial life exists and there is evidence to prove it.

The book that ignited the astronomy community has come back for everyone else

This groundbreaking book demonstrates that between the results of the 1976 Viking I lander and the latest scientific discoveries - from fertile Martian soil to microbe-ridden meteorites - there is a powerful case for life on the Red Planet and beyond. Taking weird organisms on Earth as a starting point, Schulze-Makuch and Darling explore what forms extraterrestrial life might take and where it may reside. From the noxious clouds of Venus to the methane rains of Titan, We Are Not Alone provides a captivating tour of the Solar System and shows that it's much more crowded than we previously realised.

The key here is the authors are talking about ET, not ETI-- the "i" standing for "intelligence." There's life from the galaxy, microorganisms and they ARE here, but it's questionable whether these little things form some sort of group capable of decision-making. But the science fiction possibilities for this situation seem as infinite as the guesses about where these microorganisms came from, how long they've been here or by what means they were transported.

I did enjoy this but think it could've been shorter and got to the conclusion quicker. Perhaps by adding the later chapters as appendices.

Possibly overoptimistic regarding indications of life by the Viking lander tests and Martian meteorites, but this book takes a good, well-communicated look at the geochemistries of potentially habitable worlds throughout the solar system.

Excellent summary of previous missions to detect life in the solar system. The book incorporates many of the recent discoveries of life here on earth at the limit of temperature, darkness and pressure extremes, so called extrem0aphiles. The book also makes a good case for the failure of previous Mars missions to detect life in view of the current broader definition of life we have today.
