I believe, to a great extent, in falsifiability. That means I base my theories about things that happen in the world on evidence I can support. This doesn't mean I'm above speculation, like anyone. Speculation and imagination is how we arrive at some of our most interesting findings. Further, it's how we ferret out the truth when bad faith actors are trying to deliberately conceal it. I applaud this impulse and I understand the distrust of institutions like the state, research facilities, etc, none of which have the most spotless records on explaining things to the public clearly or comprehensively. It may be that eventually evidence comes to light that makes the "lab leak" theory seem plausible. But as of now, it's mostly built on a house of cards of circumstantial strings of evidence that don't fit together well and are unsupported by the work that hundreds of researchers around the globe are doing on this virus.
What I can tell you has been more comprehensively documented and fairly conclusively supported is who originated the lab origins idea, who spread it and who has promoted it in media and in direct statements to press. Here are some useful links on that for anyone who is interested:
From early in the pandemic, on the likelihood of COVID-19 aka SARS-Cov-2 having a natural origin.
No matter where you go online these days, there’s bound to be discussion of coronavirus disease 2019 (COVID-19). Some folks are even making outrageous claims that the new coronavirus causing the pa…

From last summer, a journal article on the evolutionary path of COVID-19 that finds its antecedents have likely been around in the wild for awhile.
In this manuscript, the authors address evolutionary questions on the emergence of SARS-CoV-2. They find that SARS-CoV-2 is not a recombinant of any sarbecoviruses detected to date, and that the bat and pangolin sequences most closely related to SARS-CoV-2 probably diverged several decades ago...

On the theory of a lab leak, its refusal to die and counter-evidence against it.
Though nearly half of Americans surveyed believe the COVID-19 virus was created in a Chinese lab, mounting scientific evidence continues to point to a natural origin. The most recent research, published May 10 in the journal Current Biology, offers yet more evidence that SARS-CoV-2, the virus...

And here's a recent comprehensive overview from CNet that leaves the question open, describes why the lab leak theory has appeal and even some support and discusses some of the motivations of people who have spread this theory.
A tangle of conspiracy and politicking has complicated the investigation into the pandemic's origin.
