Hal Jordan has been Earth's Green Lantern since 1986, which means he might have come into contact with a certain metahuman at some point. DC fans have been speculating that the superhero would likely have wanted to check out an alien spaceship crashing in Smallville, Kansas when Kal-El arrived after Krypton's fall.
As is usually the case with the Man of Steel's backstory, he is then raised by farmers Jonathan and Martha Kent. And, as one fan theorized, this might be what put Hal off from intervening. They suggested: "The concept of Hal checking out the crashed spaceship in Kansas only to see a tiny baby Clark in Ma & Pa's hands and immediately backing off because he can't 'take care' of this cutie patootie of a threat, so Hal just checks in regularly as Clark grows up."
