Our lives matter because everything we do has an impact in the world. It can be something major, or something really small, but what matters is that we made an impact. This impact can affect the lives of others, in any shape, way, or form. When it comes to family and friends for example, we all have an impact on their lives, which could be one reason as to why our lives matter. Another example of why our lives are important could be the fact that we are destined to change the world for the better, or at least try to, and this is how every single one of us become meaningful to the world and the universe around us.
