It makes perfect sense – regular reindeer cannot fly and bend time, nor do they have glowing noses.
Therefore Rudolph and company are aliens.
The third eye (usually cunningly disguised under harnesses) is used for discerning who is naughty or nice and the info is passed on to Santa. There is only so much a fat old guy can do after all!

Happy Christmas to all.
