Alien Carving

This carving is hundreds of thousands of years old, and made from an unrecognized natural fiber, grown on an unknown planet. It bears striking resemblance to the old earth yin-yang symbol. Two competing theories may explain this similarity:

1. Aliens visited earth prior to the 4th century BC and influenced the development of ancient Chinese philosophy.

2. The concept of yin and yang is universal. Since yin and yang describes the fundamental interdependency of seemingly opposite forces, it may be a necessary existential understanding, in some form, in all sufficiently developed civilizations. The tapering of two circles (union) into opposed and infinitesimally small points (the finite) is one logical way to represent this understanding, and may have been developed independently by species other than humans.
