Lol they don't need horns, those are for rhinos. They need a unicorn. Whether or not those exist i don't know. I'm sure they could be made with enough effort.
I voted for Yes, the Unicorn exists. I believe that the Unicorn does exist, even if it's only in people's imagination, and just because people have never captured one doesn't mean that it doesn't exist. If I wanted to be "logical" about the whole thing, I could say that it's the people who believe in it that makes it exist in the first place. L_S
But I've talked to them before in my dreams and they said they were real. I'm inclined to believe them =/
According to Rene Descarteses quote "I think therfore I am" suggests to me that unicorns do exist if you think they do.
