You would strictly have to be agnostic about whether there is a teapot in orbit about Mars, but that doesn't mean you treat the likelihood of its existence as on all fours with its non-existence.
Galima būti griežtu agnostiku dėl to, ar Marso orbitoje yra arbatinukas, tačiau tai dar nereiškia, kad jo egzistavimo galimybę prilyginate jo neegzistavimo galimybei.
