Superman (Action Comics #1, 1938)

In Action Comics #1 (1938), a scientist on a doomed planet seals his infant son inside a hastily built rocket and fires it toward Earth^[1]. The ship crashes in open country, the baby is found by a passing motorist, and he grows up to become Superman. The original tale didn't even name the planet — "Krypton" and his birth parents were added the following year^[2]. Notably, this arriving craft predates the flying-saucer era: it is a streamlined rocket, not a disc, reflecting 1930s dreams of spaceflight rather than any later sighting.
