How did all peoples are in different emotions at same time?
Different people are affected by different things in their own environments, so they can have different emotions. For example, I may have a death in my immediate family, while you have a wedding. Your family may all be happy and mine may all be sad. However, when there is a major catastrophe somewhere in the world people all over the world share in the same emotion — for example when there is a major earthquake and a lot of people die — many people around the world feel sadness, although those closest to the quake feel sad longer. This is because they are affected more than others, and is only natural. So, people can have different or the same emotions at the same time depending on what is going on in the world.
