Just my opinion, Jesus likely existed, but surely not as a son of God. There is very little evidence about Jesus.
Some even claim Jesus was a woman and not a man, because at that time such teachings coming from a man would be considered to be comical as his (?) teachings are often female orientated (feminist-friendly?), there are claims he was a gay man, even claims he/she was handicapped etc..
Nobody knows who he or she really was - nothing is said, even not in the Bible, about the looks of Jesus, not even the gender is mentioned.
To find the truth about Jesus and what happened at that time is impossible.
Every religion which is somehow connected with Jesus tells you a different story, for example Ahmadi Muslims believe that Jesus was crucified but survived the four hours on the cross. He was only unconscious but recovered. As he was facing persecution he decided to move away direction eastwards and died of old age later in India.

There is even a Jesus Grave in Japan, in the small village of Shingo 新郷村 in Aomori, a very remote location.
Some Japanese Christian Churches believe Jesus made it up to Japan, (via India - similar to the Ahmadi Muslim belief) but those documents by Takenouchi no Sukune 武内宿禰 recorded in Japan's earliest literary texts are often considered to be nothing but a fairy tale. However those documents also mentioned that Jesus died older than 100 years and Christians were persecuted everywhere and many lived in hiding in Northern Japan.
In this village there is a church+museum which claims that many of the unique customs of the village, like the now-lost custom of drawing a cross on the forehead of infants, come directly from the teachings and direction of Jesus. Each year, a Jesus-Festival is held at this grave and thousands of Christian pilgrims and tourists travel to this site annually every year.

Shingo Village is a village located in the southern part of the southeastern part of Aomori Prefecture. There are festivals and ruins that are said to be related to the legend of the tomb of Christ and Jewish people.
