What if intelligent aliens visit us and we find they worship a god we earthlings have never heard of?

For some reason, various inhabitants of Earth have decided to worship different gods. Some worship the God of the desert. Some worship Vishnu. Some bow to Brahman. We even have various cults that worship their leader and believe that he or she is the creator incarnate in the body of a human.

If we look back through history and prehistory, it is clear that humans have worshiped hundreds of different creator gods. So if we humans have “discovered” so many gods;, it is reasonable to expect that a race of intelligent aliens might have developed a god or two just as we have. Now if their god’s characteristics happened to perfectly coincide with any one of ours, that would go a long way toward validating such a deity as being the one true god. But if their planet has a whole host of different gods as ours does, and none of theirs match up with any of ours, wouldn’t that suggest that gods are created by intelligent life forms, and not the other way around?

If you are a believer, would such a revelation shake your faith that you have picked the one true god from among the many that humanity has worshiped? If you are agnostic or atheist now, would it strengthen your conviction that there is no god? Or would it make no difference to you?
