the Earth has four different seasons because it goes through phases you see the first phase is spring what's all happy and then you get Summer where it's like super hyped for no reason and like it's going out to like parties and stuff but then you get fall you see starts getting up it's sad not having fun falling down a rabbit hole then winter comes oh winter Earth is depressed right here super sad no longer going out doesn't have any friends but then spring comes in again it's like yo wake up
