Have I ever read this before? That's how I feel. John doesn't describe Jesus baptism, only John the Baptist's narrative about it. John the Baptist says that God had revealed that the Holy Spirit would be a sign that Jesus is the one. John baptized to reveal the Messiah -- a very deliberate purpose.
The word "eurisko" (to find) from which we get "eureka" is used of Andrew finding Peter and Philip finding Nathaniel and by both of them in explaining that they had found the Christ. Who am I finding?
