OP, Jehova's Witnesses are not Christian, just as Jews or Muslims are not Christian. There is more to being Christian than believing Jesus was a cool guy.
The first criterium you need to apply is whether a religion recognizes Jesus Christ as God. Not a god, not a demigod or a divine champion, but the God who has existed before the beginning of time and who created the world. This is already where JWs fall through, they believe in a god they call "Jehova" and that his first and only creation is the archangel Michael who then went on to create everything else. Michael was then later incarnated as Jesus, and after the crucifixion the body of Jesus was destroyed and Michael was restored again.
This is absolute heresy. The archangel Michael is an archangel, not the creator of the world, but a part of Creation. All of Creation comes from God who is a Trinity consisting of the Father, the Son and the Holy Spirit, three persons who are all fully God. Not three gods and not three thirds of one god. All this is found throughout scripture and Church Tradition. The Nicene Creed was formulated as a TL;DR following the heresy of Arius. In that sense you could call it "man-made", but it is not something a committee just pulled out of their ass and then voted on.

No, they blatantly re-write the Bible to suit their heresy. This is also why JW members are forbidden from reading anything that opposes the heresy. It is also why JWs always go in groups of two, so they can keep watch of each other. Because the punishment for coming in contact with the Truth is excommunication and since JWs are a tightly-knit group (like all cults) and JW members are forbidden from keeping contact with former members, excommunication means you lose your entire social life.
