The scientific community is doing the studies, all the studies, every possibility is be analyzed & tested, even the most outlandish claims are being thoroughly tested in many many scientific studies/trials. Every scientist in any related field wants to be the one to find a cure, or find the source, or find any other relevant information on this disease (for the career advancement, the citations, the bragging rights). That the scientific community is correctly trying (and unfortunately failing) is to suppress the spread of false and/or misleading information that is not supported by the science, like the following:
1. Sensationalist press releases that are not supported by the underlying scientific paper.
2. Press releases propping-up weak new papers/studies that are less statistically powerful than the current consensus and therefore don't change the consensus.
3. The general press proping up scientific pre-prints without peer review.
This is misinformation. A group of prominent virologists wrote, early in the pandemic:
> The rapid, open, and transparent sharing of data on this outbreak is now being threatened by rumours and misinformation around its origins. We stand together to strongly condemn conspiracy theories suggesting that COVID-19 does not have a natural origin.
It's nice to _believe_ that scientists are pursuing every possible theory. But in actual reality, some scientists are demanding that other scientists not pursue certain theories. That's what's happening in the real world that we live in. Don't let your idealized mental image of "science" blind you to the facts.
