ELI5: Bertrand Russell’s analogy of a teapot to explain ‘burden of proof.’ Known commonly as “Russell’s Teapot,” “Celestial Teapot” and “Cosmic Teapot.”
gpt
Russell's teapot is an analogy that shows that burden of proof lies with whoever makes the unfalsifiable claim. If someone was to claim that there was a teapot orbiting the sun between the earth and Mars, then the burden of proof lies with them, because it is impossible to prove that there isn't said teapot.

It's often used as an argument against religion or more accurately against the notion that religion must be disproven. Since it is impossible to disprove a god, the burden of proof lies with whoever is claiming God exist.

Tl;dr if someone ask you to prove something happened, and your argument is "prove it didn't" then your argument is probably bad.
