If I limit it to existence within a closed room I'm in, then it becomes physically evident if I don't see at least one pink unicorn running around.
It is not a stretch to say that there's no good reason for you to accept the claim that a pink unicorn exists under those circumstances.
It becomes much less of a stretch when you've looked at the results of thousands of years of people combing the globe trying to find evidence for pink unicorns and they've turned up nothing demonstrable.
Many things might exist that we are currently unable to detect but the time to believe that they exist is when we figure out how to detect them and not before.
