“The bottom line is that any life form developing on a different planet would have its own evolutionary path. Another planet, for instance, would have wildly different environmental variables than Earth. Maybe it’s smaller than Earth, maybe it’s hotter, maybe the days are shorter, maybe there is less water. The fact is that with millions of small, even tiny, differences between our environments, there would be an infinite number of variations of physical form for them to evolve into. So, with an almost limitless amount of diversity, the odds of another race developing into near identical beings is…well, a mathematical impossibility.”
