Well Andre to address your only (semi) coherent point, i exist due to a multitude of processeses.Biologically life has evolved from single cell organisms to complex bipedal forms over millions of years. The physics of the universe and its impact on earth is responsible for my design. The processes of evolution and climate that shaped man does not apply outside of earth and as such any claims of humanoid creatures on Mars is pure nonsense. Indeed any life in the solar system is highly unlikely to be bipedal/humanoid. A slight increase/decrease in a planets mass would have significant impacts on how lifeforms evolve, that is of course provided every other factor that has shaped us is exactly mirrored on other planets.
