You invented the rule because you stated the rule.
I say I know because I know, but that is not something I can prove to anyone else. There are many different ways of knowing and not all of them are based upon facts that can be proven.

Definition of KNOW
No, not unless they are trying to
prove what they know is true in a debate or in a court of law.
You can claim to know there is no God and many atheists do, and I won’t tell them they have the burden of proof. Here is what I will say and have said on numerous occasions:
There are only three logical possibilities and they are mutually exclusive:
1. God exists and sends Messengers to communicate with humans (theist), or
2. God exists but does not communicate with humans (deist), or
3. God does not exist (atheist)
You can pick from the three and I won’t tell you that you have to support your choice UNLESS we are in a debate about whether God exists or not. Then I might ask you why you made that choice, but I would never ask you to prove that your choice is correct because none of the three choices can be proven correct.
