What does the Bible say about being interested in the paranormal?
It short, it tells us to stay away from it.
It would have been prehistoric man. Fire would have been the first paranormal thing a person probably saw. As far as ghosts, there are ancient texts including the Bible, Koran, and other religious texts that describe paranormal sightings. But it is safe to assume that this was the case even before we had a written language, so to say specifically what the first sighting was, would be impossible.
In a business email he writes give me a call next time your'e around is he interested in me or just being polite?
Its hard to say, but it looks like he is being a little more friendly than a business relationship would require. So yes, he's interested in you. He may be interested in you for business reasons - is he selling something? If not, if you are interested, give him that call. Keep it short, keep it light. But be careful, as always. He might just be out to take advantage of you.
