AI中文摘要：
围绕地球以外生命的探测声明常引发高度关注，因其涉及诸多重要层面。本文对比了两个高不确定性的生命探测声明，即2020年金星磷化氢探测声明和1976年火星海盗号生命探测实验。探讨了结果模糊时证据、解读及公众叙述如何相互作用，追溯了各案例的发展过程，提出了针对科学家等各方的最佳实践，强调建立透明验证途径以管理未来生命探测中的不确定性。
英文摘要：
Detection claims surrounding life beyond Earth often attract intense attention because the question of whether we are alone in the cosmos carries unusually high scientific, social, philosophical, and theological stakes. This chapter compares two high uncertainty life-detection claims, the 2020 phosphine detection claim on Venus and the 1976 Viking life-detection experiments on Mars, to examine how evidence, interpretation, and public narratives interact when results are ambiguous. We trace how each case unfolded through critique, reanalysis, and shifting assessments, and how institutional choices shaped subsequent research pathways, from long term monitoring and renewed Venus exploration to a Mars strategy centred on habitability rather than direct life-detection. Drawing lessons across both cases, we propose best practices for scientists, institutions, the wider scientific community, and science communicators, with emphasis on open science, constructive follow-up, cognitive bias awareness, and careful framing so that initial detections are not framed as final conclusions. We argue that managing future life-detections is less about eliminating uncertainty than about building transparent verification pathways that protect credibility as follow-up evidence refines the picture.
