If they were more advanced than us then they would have been here by now. If we are now exploring other planets, then they would have already done so. Or they could just be straight douche bags and have been laughing at how far behind we are with all the resources we have.
Do you realize how vast the Universe is? There could be a civilization that is tens of millions of years more advanced then us and has been traversing the Universe for millenia and they still wouldn't have mapped the entire thing and they may not have stumbled onto us yet. Or if they did, they may not think we are ready to be contacted yet.
There could be advanced life in our own Galaxy that hasn't found us yet, let alone the Universe.
