There are many theories to explain the great unknown. Some people turn to science, others religion. And of course there are those that just shove both aside and say that life as we know it just happened (though this theory turns back to science in the end (see Darwinism.) Many different countries and races have had religion for as long as there has been recorded history, and in the more recent times of intercontinental travel, there have been reports of "black holes", places where boats and planes just disappear off the face of the earth. The most famous being the Bermuda Triangle.
