>>18526832its not a CGI animation of "what they said happened" it was the live feed the indian version of NASA watched themselves in their command center and cheered when it finished.
Pretty much the same thing for the mars rover landings.
The only "why" is why dont you have the reasoning skills to understand why theres not a 3rd person video of the lander landing and instead they would rely on a user interface to give them metrics of whats happening.
This is pretty basic critical thinking skills but today since so many peoples brains are turned to mush they have to jump to vast conspiracies rather than logical conclusions.
