1. Converting an ET Alien & 2. Is Their Food Kosher
Question
I have a theoretical question:
Consider there are non-human persons that exist, created outside this world of earth, but never revealed to us, which possess intelligent thought.
Would it be possible for one of them to convert to Judaism (Giur, be considered a part of the Jewish faith by all)? Consider that they can distinguish good from evil.
In the same vain of questions - consider they have food, very different to our, and they brought some to us.
How could we distinguish which is Kosher (animal, plant, fish or none) and which is not?
