The key to your question is to make you understand the existence of past lives and future generations. You don't believe in past lives and afterlife. I believe that people will be broken after death and will not continue to the next life, so you came to this world, and you don't admit that this is the continuation of previous lives. But Buddhism believes that people have past lives and afterlife, because the mind will not be destroyed after death, and your karma will lead you to the next reincarnation. What do you think? We are all ordinary people, not saints. We can't take you to visit heaven or hell, but we can find clues from our daily observation. For example, why are some children as old as the village head gifted in learning English and others gifted in learning mathematics? Growing up in the same family, why do you like carrots and my brother likes potatoes? What we take for granted but ignore is the habits brought by past lives. If there is no afterlife like you, then every newborn child should be the same and will not have his own preferences. However, this is not the case. Some dolls love to cry, some love to laugh, some love to play with cars and some love to play with guns. All this is the result of previous karma. From this, you can understand that the good and evil done in the past life will lead to the pain and joy in this life or the next life. So, although you are in pain now, you will try to do good deeds. Now you enjoy it, and you will try to cherish your blessings.
