If the planet is larger , the pull of gravitational force would be sweller which would affect the organisms liv ing in the planet in a sense that hydrogen w! ill not be able to outflow from the atmosphere .

On the other hand , if the pull of gravity was less , oxygen would escapism from the atmosphere which would make it impossible to sustain life . The planet s rotation period is also perfect otherwise on the whole kit and boodle life would not be able to survive (A orbiter Perfect for deportmentThese are just or so of the factors that describe wherefore the Earth is perfect for the sustainability of life , peculiarly the complex life forms . Although there are discoveries that may resurrect that there are other planets that may be alike(p) to the Earth that m ay support life , it is difficult to actualize because of such great distances .
