Agnostic: a pointless term?

[YGninja]

...a unicorn would have to exist on a planescape, as all other equines do. They would also have to have a sizable, sustainable population count. We would therefore have discovered them by now, don't you think?

Not necessarily. Gorillas were myths/legends for quite some time.

Explorer Paul Du Chaillu was the first westerner to see a live gorilla during his travel through western equatorial Africa from 1856 to 1859. He brought dead specimens to the UK in 1861

(Not to suggest that I believe that unicorns exist only that the particular line of reasoning is invalid.)

Biblical Unicorns do exist, today they're called Rhinoceros.
At the time of the writing of the King James version, Rhinos were called Unicorns.


U'NICORN, noun [Latin unicornis; unus, one, and cornu, horn.]
