Do you believe in the Lochness Monster? What about Bigfoot? Chupacabra? Mothman?

I believe that if hypothetically the Lochness Monster is/was real then it would've been a plesiosaurus that got stuck in the loch when the continents started moving but the chances of a prehistoric dinosaur surviving all this time is highly unlikely. Bigfoot is possible but you also get people making hoaxes up that they have seen bigfoot prints when they made it themselves. Chupacabra and Mothman I don't believe is possible at all. All of these are myths made up centuries ago by humans making mistakes in what they see to be honest.
