The emergence of the first life on the earth is now established as an early event, and closely related to the evolving earth. Laboratory experiments examining possible chemical events have revealed a multitude of plausible pathways. Lack of knowledge of the primitive terrestrial conditions contemporary with the evolving prebolic organic chemistry limits reconstruction techniques. The primitive earth's aqueous history is essential to unraveling this problem. Based on our current knowledge of other planets of the solar system, we do not expect close analogues to the early earth. We still do not know if there was a second origin or if only earth has life. This may depend upon the question of the survival of information bearing chemical systems in a dynamic or chaotic environment and the chemical protection afforded within such a system. Water is the central molecule of controversy: the blessing and the curse of the chemist. New and novel chemical mechanisms and systems abound.
地球上首次出现生命现在已被确认为早期事件，并且与不断演化的地球密切相关。研究可能的化学事件的实验室实验揭示了众多合理的途径。缺乏与演化中的前生物有机化学同时期的原始地球条件的知识限制了重建技术。原始地球的水的历史对于解开这个问题至关重要。基于我们目前对太阳系其他行星的了解，我们预计找不到与早期地球非常相似的情况。我们仍然不知道是否存在第二次生命起源，或者是否只有地球有生命。这可能取决于承载信息的化学系统在动态或混沌环境中的生存问题以及该系统内提供的化学保护。水是争议的核心分子：化学家的福音与诅咒。新的和新颖的化学机制与系统比比皆是。
