I guess it would depend on where they're at with their evolution, and whether or not they were ever superstitious in the first place.

NO, other beings are more in touch with Nature than humans are. We have that little six-sense that tells us life is everlasting and Nature needs help from us in making this happen. So man create all of the guideline by which man should follow in order to attain everlasting life. The mistake humans make is trying to tell other humans how to attain everlasting life but with fear tactics. Humans need to "Stay in their Lane". There is no Heaven or Hell for man to put man in, when he came by way of neither.

I look at the vast size of the Universe and think that we couldn't possibly be the only place in it that has life. As to what other life might concern itself with is only up to our own imaginations.

We do not know

I am unaware of the actual answer, however, if the scientific community has used agreed upon equipment to test and/or survey various beings, and is able to sufficiently correlate the results to a well understood and agreed upon conclusion, then possibly. Prepare your tests, gather a few subjects, and the necessary brain imaging equipment, and be sure to get peer reviewed...lol
