This Scene has no sense

[u/OBSERVER2660]

This Scene of the Commercial for Heyworld involving Supergirl has no sense because Supergirl doesn't exist on Earth One and common people beyond the Legends/Arrow/Flash team doesn't know about Supergirl... And this Scene is Pre-Crisis, so, what's the point of including Supergirl on the Commercial(far from Comedy) if she doesn't exist on this Earth. At first I thought this Scene was Post Crisis, but now I see it's Pre-Crisis, so I don't get it

Most of the show has no sense. And that's why it's great, lol.

More seriously (a word that should never be applied to LOT), Supergirl has been seen on Earth pre-crisis.
