Question: why can't we live on any other planet except earth

Hello Tai-se!

I guess it depends on which resources are available on each planet…apparently our Earth was optimal, in terms of air&soil composition, water availability, to allow life to develop and evolve! We might not know yet that there is already something/somebody else, maybe from another species, that developed and evolved on other planets under different life conditions!
