What Can We Reasonably Predict Concerning Alien Religion and Ethics?

It is very easy to be pessimistic concerning what we can know of possible aliens, much less what we can know of their religious or ethical beliefs. Nevertheless, I make the attempt by laying out a set of assumptions consistent with our best science and then use these assumptions to make reasonable inductive projections. The results are, unsurprisingly, but at the very least can serve as a critique delimiting what cannot be said as much as what can. Nevertheless, I hope that a few of my conclusions will prove interesting as points of contention if nothing else.
