Conspiracy theories are contrarian guesses which have no evidence to back them, which is true in this case. It's not impossible that it did originate in a lab, of course - the preponderance of evidence suggests otherwise. It's great that there's been an investigation opened and hopefully they are able to determine the truth.
Here's a good article that explains the dangers of these types of conspiracies that I'm sure you won't read because you are unable to process anything that doesn't align with your "critical thinking ability"

General Mark Milley, chairman of the Joint Chiefs of Staff has said that US intelligence has looked into the possibility that the coronavirus outbreak could have started in a Chinese laboratory, but that the “weight of evidence” so far pointed towards “natural” origins.
As with an conspiracy theory, it's near impossible to prove that it isn't true, but to prove it true, all it takes is one piece of actual evidence. Sorry, having a lab 10 miles away from where the outbreak occurred is not evidence.
Correlation ≠ causation
All this being said, China has not been honest at all about many things regarding the outbreak and I'm hoping we'll have a definitive answer in the future, but would be surprised if we did.
