When being a good thinker and sceptic it’s important to know who has the burden of proof in arguments. Burden of proof is simply who has to provide the evidence for their position. This can be seen in the American justice system. The prosecution gets the burden to proof to show that the person on trial is guilty. If the lawyer was to demand the defendants to prove that he didn’t do it, he/she would be shifting the burden of proof.
In other words, the burden of proof rests on the person making the claim. If someone claims that God exists, the burden of proof is solely on them. But if the other person says the God doesn’t exist, they have the burden of proof as well. But if the person disbelieves or doesn’t know that God exists, they don’t hold any burden of proof. Saying I believe X is false is different from saying is I disbelieve that X is true. In other words, not guilty is different from innocent. The same happens in football when they are reviewing the play. The play can be confirmed, the play can stand as it is, or the ruling can be overturned. To put it simply, if there’s not enough evidence on the field to overturn it then the ruling on the field stands or not guilty. But if there is enough evidence, then the play is overturned.
If someone says, “I believe in Aliens. Prove me wrong. You haven’t experienced aliens, but that doesn’t mean they don’t exist.” The problem is that I shouldn’t have to prove them wrong. I can just take the agnostic position on the claim. They are asserting that aliens exist, so they must provide evidence for their claim because it’s a claim that goes against all of our experiences. The latter claim regarding existence is true. However, this seems to be misrepresenting the skeptic. The skeptic will say that they have no reason to believe in aliens because they are suspending judgment, not that aliens don’t exist. Sure it might be possible that aliens exists, but that’s not a reason to believe in them. It might be possible that I will one day be a billionaire, but that’s not a reason or evidence to believe such a proposition.
