Nature and unfairness

life is inherently unfair by design and who gets the better end of the deal is really random/up to chance. for example, it's much better all around to be a lion than a zebra, but someone has to be a zebra. nobody asks you - would you like to be born a zebra or a lion - nature decides. actually, nobody asks you if you even want to be born, it just happens. there is always someone who is better off than you and worse off. but it's not because of you, nor is it your fault. it is simply your "destiny". things are the way they are and you are the way nature meant you to be. natural question then is why. i don't think anyone can fully answer that because it is beyond the scope of human understanding. why is there a planet here and not empty space. this could've easily been just an empty spot yet there is a planet here. why? i don't know. it doesn't serve any particular purpose in the universe. if it was gone tomorrow, it wouldn't matter in the large scheme of things. i keep thinking why, but I really don't have an answer. You could say - so humans can live, and life can exist. Then that makes nature a "good guy". But if nature is so great, why not have 20 planets next to each other - 20 times better, right? Or, then, why do living things suffer at all. Could be an utopia with no suffering where everyone is happy and lives forever. but it is not. and we don't have an answer as to why.
