If the planet is larger , the pull of gravitative force would be sweller whic h would affect the organisms living in the p! lanet in a sense that hydrogen will not be able to outflow from the atmosphere .

On the other hand , if the pull of gravity was less , oxygen would endure from the atmosphere which would make it impossible to sustain life . The planet s rotation period is also perfect otherwise intact kit and boodle life would not be able to survive (A orbiter Perfect for vitalityThese are just roughly of the factors that describe wherefore the Earth is perfect for the sustainability of life , in particular the complex life forms . Although there are discoveries that may show up that there are other planets that may be hom ogeneous to the Earth that may support life , it is difficult to establish because of such great distances . Scientists can only make assumptions ground on distinguish but now , the only planet that is known to sustain human life is the EarthWorks CitedOnly Earth Supports Life . Springboard Magazine .
