I think we should wait until it is confirmed whether or not that the supergirl timeline is part of the Arrowverse timeline. I feel like if Superman or Supergirl existed in the Arrowverse, they would have at least gotten a mention at some point on the series. I haven't seen any episodes of Supergirl yet, but from what I can gather Superman has been around a while in that universe.
