Ok, I know you're trying to piss a particular person off, but that just isn't true....

Marvel Jr, mary marvel and the whole family were introduced before superman's were..so in effect superman in the silver age was ripping off captain marvel.

The fact that he had a cape and was super strong is the only similarity...

So in effect, captain marvel was the character that initiated the silver age of DC, because Capt Marvel was selling more books than any other character for nearly a decade...
