In addition to 1) Jesus claiming to be God, 2) Jesus performing miracles, and 3) Jesus being viewed as divine by those around him, Jesus also fulfilled many prophecies in his life, death, and resurrection.
Remember that the Bible is a collection of 66 “books” written by about 40 authors in several languages over the course of more than a thousand years. How these writings came together to weave a consistent narrative is miraculous. One big example of this is that many predictions (or prophecies) recorded in the Old Testament were fulfilled hundreds of years later (or sometimes over a thousand years later!) in the New Testament.
