Ugh, that episode is so fucking stupid. “We wanted to pass information down to our creations, but we hid it in a puzzle for no apparent reason and just hoped that all the pieces of the puzzle would evolve into spacefaring civilizations that will all work together to solve the puzzle.” And that didn’t even happen because one of the pieces was on a world which didn’t have much life on it and it got intentionally destroyed during the race for all the puzzle pieces.
