There are many open philosophical issues in origins of life research. Several of these are centered around the explanandum in question and epistemological limits to our knowledge. Researchers differ, for example, as to whether the purpose of origins-of-life research is to discover how life could have originated or how it did originate (Scharf et al. 2015, Mariscal et al. 2019). Some steps in the process could have been chancy, others could have been deterministic but highly contingent, still others could have been the only way life ever originates anywhere in the Universe.
