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 careerThese are just some 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 grow that there are other planets that may be convertible to the Earth that may support life , it is difficult to substantiate because of such great distances .
