Do you believe unicorns exist?
If you don't believe they exist, how could you say they don't?
Furthermore, Unicorns are mentioned in the Bible: therefore they must have existed.
A few years ago, a 'Unicorn Lair' was found in North Korea.
Mish & all her ilk had better pray that the remains of said Unicorn was found with books around such. The archaeologists in Pyongchang said they'd found skeletons of Unicorns, so who are the OP etc to doubt the veracity of their claims? Frankly, "My Little Pony: Friendship is Magic" being a documentary is the least of their problems. Why?
North Korea says that Kim Il-sung controls the weather. Better start praying to him then, Mish. The grandfather of Dim Dong Dumb existed.
Unicorns? They have Chollima: a Pegasus. Better start worshipping Zeus & co., Mish: as the ancient Greeks were right all along.
