Nooooo Elon was joking when he said it was CGI. BURP then played on this joke to make an elaborate April Fools joke out of Elon's joke.

Think about it: the space station has received supplies from SpaceX. Couldn't happen if it was CGI

Some launches and landings have failed, have been recorded live and reported by hundreds of news agencies around the world. Can't make everyone fake the same story. And CGI missions wouldn't have blown up or missed the landing the mark and fell into the ocean.

Elon made the joke as a jab at the conspiracy theorists who were claiming that very thing anyway, same as the NASA moon landings.
