As the methods and technology astronomers use to search for evidence of life on other planets advances, there is increasing tension between the optimism of this search and the reality of what, if anything, would constitute an unambiguous detection of life. In this talk, I will describe the techniques astronomers are now using and will use in the near future to search for life on other worlds, their limitations and false positives, what assumptions these searches are based on, where the “hype” comes from, and why even skeptical scientists continue to be optimistic that Earth is not the only biosphere.
