Is it merely coincidence that Jesus has similar characteristics to many other gods before him?

No, much of the Bible is copied from older myths of other cultures. Jesus is not the only thing copied.

Jesus is not a god but an advanced soul indeed . Now resides in Rome where he is much needed though he visits USA quite often

Jesus Christ Was Is and Will Be the First and The Last. If there are similarities, then it is no coincidence nor any surprise when Juan considers all men were made in the image of God who loves my Justice and my Righteousness

<Can More Than a Conqueror Khan Juan DuMore Good in the Name of The LORD YaHaVaH Who Was Is and Will Be ur God The Righteous Tsalvation of Justice Anointed Jesus Christ Tzedekelizedek HaMashiach, a High Priest Forever and Ever According to the Order of Melchizedek.>

No. Jesus is considered an Avatar (Divinity Incarnate) in many Eastern faiths, which recognize the spiritual truths all religions share in common. It is typically a Western concept that there is only "one true faith", which like why western societies are so poorly educated spiritually. Lord Krishna, the Jesus figure of the Bhagavad Gita, name means 'All Attractive', and was translated into the Greek word 'Kristos', which became 'Christ' (or 'Anointed') in Aramaic, the language Jesus spoke.

Both are considered to be Avatars of Lord Vishnu (The Supreme Personality of God), who comes to counterbalance the negativity of mankind, appearing in the time and place it is most needed in the world. Among immaculate conception, and healing abilities, common to the Great Avatars are, the absence of ego and sin, performing miracles, and the founding of a great religion based off of their life and example. The Avatar is usually given a nickname associated with "savior" or "restorer".

Many Avatars also include, Lord Rama, Zoroaster, Moses, The Buddha and others.

Except, no other gods ever declared things to come, came and fulfilled them, proclaimed them as fulfillment of what he declared long ago and was witnessed by 1000s.

No. Those are what inspired his story.

Even the prophecy of being born of a virgin was taken out of context.

Isaiah 7:14 refers to a young woman of marrying and child bearing age (Almah), NOT NECESSARILY a virgin.
