In history, there were many people who were suspected to have transmigrated, such as Zhuge Liang in China, Pharaoh in Egypt, Modi in India, and so on. However, the authenticity of these characters was controversial because there was not enough evidence to prove that they were really transmigrators. There was no conclusive evidence in the scientific community regarding the existence of transmigrators. Although some people had proposed some assumptions such as time travel, parallel universes, etc., these assumptions had not been sufficiently verified. Therefore, the existence of transmigrators was still an unsolved problem. Although the existence of transmigrators has yet to be confirmed, we can learn from the experiences of these historical figures and use advanced technology and innovation to explore the possibilities of the future.
