What is the truth behind Dr. Heinrich Kusch’s claims?

I first came across Dr. Heinrich Kusch and his work a few days ago. On one hand, he says things that seem plausible without much doubt (e.g., that the "12 Apostel Zeche" dates back over 60,000 years and that the discovery of artifacts and inscriptions requires a reassessment of human history via C14 dating).

However, these stories about teleportation, reptilians, and apparitions in photos are so absurd that they essentially call everything he says into question. I get the feeling that he is misusing genuine Neolithic discoveries he may have made to confirm his fantasies and profit from them.

Does anyone here know if he has ever been definitively caught presenting a falsified find?

Here is a presentation by him and his wife:
