Seeing back in time

IF, just if, looking towards the edge of the Universe we are seeing back in time does that mean aliens looking IN are seeing into the future ?

No.  Whichever  direction you look in, you are seeing the universe as it was at an earlier time. This is true for all observers regardless of their location. (ie the aliens are seeing us as we were, not as we will be.)  There is also no evidence that the universe has an edge or a directionality such that we could be  "looking out or in".
