How can Matthew 28:19 be explained?

I've been studying the Bible recently and came across a verse that has left me feeling a little puzzled. In Matthew 28:19, Jesus said, "Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit." As a 14-year-old, I'm trying to understand the significance of this verse and how it relates to my own faith. I've been discussing it with friends and family, but I'd like to hear other perspectives as well. What do you think Jesus meant by this statement? How can we explain the meaning and implications of Matthew 28:19 in a way that would make sense to someone my age? I'm curious to hear your thoughts. Thanks!
