Well first,:

>there is no reason to trust any media or NGO to be truthful in that regard.

So if there are facts, you cannot believe them and OP doesn't.

And Second:

For arguments stake, let's assume that is correct and there are zero facts. So what can you conclude?

Nothing! It's possible there was a lab leak, it's possible there wasn't, we just do not know. That would be a fine conclusion.

So why has Op decided one possible conclusions is "much higher (probability) than" the others?

We don't know if there is a god or not. So concluding one particular religion is correct is dumb. The same applies to people claiming one theory or another is right re Covid Origins.

That is where the disregard for (lack of) facts comes in. If you don't know, you don't know; you don't get to decide with certainty what reality is because looking is too hard.
