People cannot decide what lives exist or not, they may exist in hiding, they may be extinct, many possibilities are out there and no one can fully state the facts, it is like asking if there is life elsewhere in the galaxy, there is a 50 50 chance that its true and false. Never give up believing, just because they say its a myth doesn't mean it is.
It depends on what you call a unicorn. There have been "unicorns" in fairs and carnivals that were single horned goats (due to a genetics problem) and it has been suggested that the stories of unicorns were based on sailors stories of rhinos. So, yes in a way there are real unicorns.
in Ontario science centre they had a circus theme on main floor and in 1 of the tents they showed a REAL unicorn skull. and there is a type of animal in either Africa or Austrailia. they were not called unicorns though. i belive they look like gazzeles only with 1 horn.
A unicorn means a horse that has a only one horn ,so horse is real ,and some of them do have horns .usually males ,because just like us humans we all may have similarities,but we all are not completely the same
