Honestly, I love to think they are out there. I don't know all the answers, but I know there are a lot of things I don't know, which is why I love the mysteries left in the world (fairies, big foot, loch ness monster, etc). There is still SO much we have to learn, and so much of our world left to explore, why wouldn't there be plenty of things out there we don't know about? Honestly, I just like to think they are there because it means the world still holds magic to me.
