The Engineers Decoded: Did Life on Earth Come from Space?

In the opening of Ridley Scott's Prometheus, a giant Engineer breaks apart in a waterfall, and life on Earth begins. In episode 7 of Creature Decoded we ask the real question behind it: could life on Earth have come from space?
From Francis Crick's 1973 directed panspermia paper to a Martian meteorite found in Antarctica, the Murchison meteorite, and the asteroid samples from Ryugu and Bennu that contained 14 of the 20 protein amino acids and all five nucleobases. Plus bacteria that survived three years outside the space station, the ancient viruses hiding in your own DNA, and whether giant Engineers could exist at all.
