I make decisions based on facts, evidence, and common sense. Using those three, it is fairly easy to understand that this virus came from a lab.
You believe you make decisions based on facts, evidence, and common sense. This does not guarantee that your decisions are always correct.
Have you ever considered that two things can be true at the same time? In this case, that the COVID virus could have accidentally leaked from the Wuhan Institute of Virology but also because of natural zoonotic transmission?
I previously mentioned consensus generally favors a natural zoonotic origin. You asked what consensus. One would hope that to conclude that the COVID pandemic is the result of the Wuhan lab leak you would have investigated other possibilities and therefore known that the leading consensus among major health organizations, including the World Health Organization is that COVID is of zoonotic origin. Zoonotic spillover is also the consensus of the scientific community at large.
COVID is a virus like SARS, MERS, and Ebola, and the vast majority of emerging infectious diseases in human history are zoonotic. The virus "Monkeypox" or Mpox was first identified in captive monkeys used for research in 1958. But there are also many viruses resulting from accidental laboratory escapes, such as the Russian Flu and the Marburg virus, and many other viruses.
