I worked for many years in a lab, the accidental leak hypothesis was and still is what I consider the most probable. Calculate the joint probability of everything we know about the origin of SARS-CoV-2 happening and it should be obvious that the "lab leak" should be _thoroughly_ investigated before dismissing it.
p(Epidemic started in Wuhan) * p(origin in market right next to lab) * p(lab is one of 3 in the world to conduct gain-of-function research on conronaviruses) * p(lab scientists were notably sick prior to outbreak) * p(no accident ever happening in a lab) * p(et cetera) = very small number.
That's not evidence per se, but it does show you how probable a human error is.
