In the case of SARS-CoV-2, there are multiple scenarios that could, in principle, explain its origin with varying degrees of plausibility based on our current understanding. These scenarios range from natural zoonotic spillover to those that are associated with laboratory work. Scientists need to be able to evaluate all of these scenarios, and all viable hypotheses, with credible data.AI Verified (Jun 15, 2021)

The quote is directly about SARS-CoV-2 origins and explicitly contrasts natural zoonotic spillover with laboratory-associated scenarios. It does not endorse a lab-origin conclusion; instead, it signals abstention by saying multiple scenarios should be evaluated with credible data.

The source says SARS-CoV-2's origin "remain[s] unknown" and that scenarios range from natural zoonotic spillover to laboratory-associated work, urging evaluation of all viable hypotheses. That is neutral/undecided rather than favoring a lab incident over natural spillover.
