One could argue that a social alien species would have some underlying god concepts similar to many of ours. It would be the underlying explanation for not yet understood things and it would probably suggest a golden rule type law.
There is even some possibility of some of the local variants suggesting a sacrifice as this honours altruism.
However, what is astronomically unlikely is any reference to a Jesus like figure formed in the image that is more like us than the aliens (in the image of the true god). This would indeed be interesting and require some pretty hard thinking to explain.
I'd suggest that the right similarities without enough would support the idea that religions are evolutionary by products or advantageous to societies.
This would all have pretty much zero effect on our religious thinkers. They've all managed to ignore any part of other religions lots of times except there they could conjure up some support for their views (e.g., flood myths).
