The miracles Jesus preformed cannot be preformed by magic, it simply is not possible. You cannot raise the dead, heal those born blind or the leaper by magic. Jesus even made out of clay birds and gave them life. And people witnessed these signs and miracles.
You started this off with a huge swath of assumptions which can easily be disproven by the Torah.
Firstly, You can do all of these things with black magic, at least the Torah tells us it is possible and forbidden. The Torah specifically warns against a spectrum of dark arts, idolatries, and witchcrafts which all fall into this category.
Let no one be found among you who consigns his son or daughter to the fire, or who is an augur, a soothsayer, a diviner, a sorcerer,one who casts spells, or one who consults ghosts or familiar spirits, or one who inquires of the dead. (Deut 18:11)
The Oral Torah explains that this also involves the raising of the dead (necromancy). Rashi specifically touched upon this.
Rashi: "or a charmer"
One who collects snakes, scorpions or other creatures to one place.
"a pithom sorcerer" - one who raises the [spirit of the] dead, and it speaks from his [the sorcerer’s] armpit.
"a yido’a sorcerer" - one who inserts a bone of the animal called yido’a into his mouth, and the bone speaks by means of sorcery.
"or a necromancer" As, for example, one who raises [the dead spirit] upon his membrum, or one who consults a skull. (Source)
You cited the story of Jesus molding a dove from clay and animating it to life. This is a known concept in the mystical traditions and it relates to the sages having discovered divine processes for animating life into clay. The Golem of Prague being one of the more famous stories of such a creature.
Jesus did nothing that distinguished himself from various other figures beyond presenting himself as a false fulfillment of the Mashiach prophecy and declaring himself God in flesh. Miracles are miracles, and they all belong to Hashem regardless of whose hand is used. Dark magic is dark magic regardless of what you use it for and to whose benefit.
Beyond that point, we know for a fact that the writings of the New Testament were written hundreds of years after Jesus walked the earth.
The earliest manuscript that exists is dated 150-250 years after Jesus. Since this book was rehashed and edited so many times, King James organized a council to formulate a "finalized" and uniform version of the book in 1611. (Seriously, 1611)
The Council of Nicea (325 CE) (which canonized the NT) edited out various other writings and contradictory narratives and books in order to create a uniform text. So many different folks had so many different interpretations and themes of what exactly Jesus was and what he did that they had to have the Church literally hand-pick what stayed and what went.
Jesus was claimed to have communed with an army of dragons in a deleted Bible story. (The Gospel of Pseudo-Matthew, Chapter 18)
Jesus straight up murdered a child. (Infancy Gospel of Thomas 4:1)
Jesus convinced a snake which had bitten a child to suck out its poison. (First Gospel of Infancy 18:13-16)
So can you see my issue with the claim of "Look at the amazing things that Jesus did! Look at everyone who witnessed this! It has to mean something!"
But then you ignore the fact that if the original New Testament had not been edited in the first place, you would have a Jesus who was a dragon-taming, snake- conversing, child-killing whatever. We know nothing about Jesus beyond his name and beyond what the Rabbis spoke about him. The New Testament is a mishmash of conflicting stories and eyewitness accounts and themes which not could not give a clear picture of what Jesus was thematically, and which also blatantly misquoted the Torah to meet its own needs.
“For they did not continue in My covenant and I did not care for
them…” [Hebrews 8:9]
“My covenant which they broke, although I was a husband to them…”
