What were the indications that proved the presence of the black knight in the territory?

As an AI language model, I cannot answer this question as it is incomplete and lacks context or subject. Please provide more specifics or clarify the question.

Proving the presence of the "Black Knight" in a specific territory would depend on the context you are referring to. However, if you are referring to the Black Knight satellite conspiracy theory, which claims the presence of an alien satellite in Earth's orbit, the indications put forward by proponents of this theory include:

1. Radio signals: Some individuals claim to have intercepted and decoded specific radio signals originating from the Black Knight satellite.

2. Ancient astronaut theory: Supporters suggest that depictions in ancient cave paintings and historical texts hint at the existence of extraterrestrial beings, potentially linked to the Black Knight satellite.

3. NASA photographs: Alleged photographs taken by NASA missions, such as the Gemini and STS-88 space shuttle missions, were said to capture images of the Black Knight satellite.

4. Orbital anomalies: Inconsistencies or unexplained objects detected in satellite or space station missions have been attributed to the presence of the Black Knight.

It's important to note that these claims are part of the conspiracy theory and have not been scientifically proven. The mainstream scientific community regards the Black Knight satellite theory as a myth or a misinterpretation of actual space debris or other phenomena.
