It's a mistery

Today i'm going to write about a thing that I think it can be called a mistery.In the world there are a lot of things that are considered mistery.A mistery for me is a thing which happens sometimes in the front of the cathedral.Sometimes there are dead birds in front of the cathedral's gate which don't have a head.I don't know how their head is being separated but i think i have a theory.When is dark night the birds can't see they accidently flew towards a statue and their head is separated from their body and the head is eaten by some animals.Another mistery which I'm interested in is the mistery which is in the Lake Loch Ness.Some people say that in this lake lives a sea monster who's name is "Nessy".They think she has a family and they live in this lake.I was talking with my classmates about the things which happen in the world and which are considered to be a mistery.Egzample: What do you think there are aliens living on our planet?.We discussed that there's a possibility that there are aliens who live on our planet but the government don't whant us to know the real truth.
