My guess is that we are martians in the sense that we are affected by the energy of mars, but of course we are more affected by the earth because we live here, and the moon is closer, that is why we are such emotional creatures. Some of us are more influenced by mars, others more influenced by venus and so on. In a way, we are from everywhere because we are everywhere, remember, we are not this body, we are energy, we are spirit, its all a matter of where our consciousness is how that environment affects our perception and reality.
