Imagine I make the following claim:
- There is a teapot - which is too small to be seen by telescopes - and it orbits the sun somewhere around mars.
Let's say I don't offer any proof or evidence for my claim. Would you take my claim to be true?
This analogy was put forth by Bertrand Russell (1872-1970), who wanted to demonstrate that even though no one can disprove the existence of such a teapot (since we said that it's too small to be observed anyways), he would expect no one to believe in its existence either.
