From a catholic or protestant background things get a little more murky. Prometheus is the Greek rebel who brought mankind fire, so he is usually considered analogous to Satan. But it also must be conceded that it advanced mankind.
Heck in the garden of Eden the serpent traded "advancement" for mankind's innocence. In other words if there is a species offering "advancement" and another trying to repress, the Christian reading of the situation would be the God/angels faction repressing and lucifer/demon faction advancing. So any "aliens" offering us advancement it would be difficult to trust
