This doesn't prove that planets form from accretion disks. They've simply found a planet in a system with an accretion disk. It could be used as evidence supporting planet formation for Macroevolutionists, but it definitely is not proof.

Quibble -- they've found a planet (a gigantic one) around a star, and a disk of dust and debris around the same star. :')

The planet is in an elliptical orbit that carries it as close to the star as Earth is from the Sun, and as far from the star as Jupiter is from the Sun. Epsilon Eridani is a young star, only 800 million years old. It is still surrounded by a disk of dust that extends 30 billion kilometers from the star.

For that matter, the orbit of the planet, along with the lack of proximity to the disk (which is over 18 billion miles from the star), suggests either a capture origin, expulsion, or collision.
