On the reality of Jinns
They are very territorial and apparently prefer to keep themselves away from any place lit (by light visible to the human eye). Thus, the human industrial revolution and widespread availability of electricity has made these being much less social and their appearances are now usually reserved for petty annoyances to humans. However, we really know they still exist because we can see meteors chasing them now and then. The meteors chase them at speeds of 30,000 miles per hour without a moment’s lapse, somehow disallowing these otherwise super-duper beings to stage an escape using one of their otherwise present super powers.
Communicating with these beings is quite hard and usually requires a person specialized in such to do so. Invocations from any one of the millennia old popular literature help initiate the communication while fire and water are often used as assisting tools. Even then, the presence of these beings can never be observed directly and any communication has to be channelled through a human medium (who effortlessly performs the miraculously hard job of vocalising their thoughts into human understandable speech and vice versa). These beings are hard to deal with, hard to make friends with and apparently can't be reasoned with. Interestingly, however, the notion of good and bad is present among them as well, although their evil mofos are so trigger happy that we have to be (only) particularly careful with mundane activities as spitting or throwing things into the dark.
These beings are known by many names - genies, jinns, ghosts etc - but we all share an unspoken understanding of exactly what these "beings" are. We are unable to see them, hear them or feel them - utterly unable to do so even with the most modern advanced tools and techniques. Yet the reality of their presence and existence is not something that just cannot be denied... no sir, not at all... just like the unicorns, the leprechauns, sasquach, loch ness monster, bigfoot, fairies, rannamaari and avattehin!
