Hi there,

You don't have to upvote. It is much more important to share thoughts and I salute you for that!

The short answer is: I don't know. For the long one, you'd have to bear with me...

Yuval Harari is a World famous historian and a professor at Jerusalem University. I enjoyed his lectures and agree with his main points in general. However, I agree with him, not on all his points. For example, he feels that most wars are caused by the disagreement in the Disagreement in the fictional stories that both sides cannot agree on. This argument fits with religious wars or with the Middle Eastern conflict. However, I feel that many wars are caused by purely economic reasons, the control over the trade routes, colonies, etc.
All this to say is that my personal opinion is not always the coincides with those whom I quote.
In regards to spirits… Personally, I have never seen or experienced them. That is not to say that other people didn’t see them or experience them. I simply don’t know. More so, spirits are not material, but energy entities and I never studied them, or researches about them. Thus, I can offer an intelligent opinion on that subject neither con nor pro. )))
