is it there any truth that the romans kings created jesus on their own imagination in order to unite all the people

Answer 1

No. Theories about the non-existence of Jesus circulate every now and then through articles in newspapers or on TV specials. While people disagree often about the identity of Jesus, very few serious scholars deny the historical existence of Jesus of Nazareth. Non-Christian documents, such as the works of Josephus (first century) and Tacitus (early 2nd century), attest to his existence.

The argument that there is no evidence for his actual existence is a great illustration of something called "confirmation bias"--historical evidence in favor of his existence is ignored, and throwing out all the pieces of evidence is seen as "proof" of the absence of evidence.

Who is Jesus of Nazareth? That's another question altogether.
