>>16390525If something exists, you can find evidence of it. For example, if someone says there’s a cat in the room, you can look around and find the cat to confirm it. If someone says there’s no cat in the room, proving this is much harder. You’d have to search every inch of the room and even then, someone might argue that you just didn’t look hard enough or missed a hiding spot. In other words, proving something exists is easier because you only need one piece of evidence. Proving something does not exist often requires you to rule out all possible evidence, which can be impossible.
