I have given the discovery of other Earth-Like planets beyond our solar system a lot of thought. I don't think another world would evolve like us. Something fundamental would have to be different to create a different culture and history that would be odd to people of Earth. I've designed a spin-off of humans where evolution sent them in an entirely different direct by simply examining a civilization of women having physical superiority over the men of their world, since their history began. Has the discovery of other Earth-Like planets influenced you?
