That's a very weird and mysterious answer, it seems to very much be an occult symbol based on my research, but I dunno what you mean by it's not occult as much as Christianesque when it spans time periods BEFORE Christianity and cultures that were not Christian. For example, the Egyptian pharaohs would sit on a cube, some believe that it means "power" or "rule" or something like that. So.. I'm not really so sure your claims line up with all that, but perhaps you have some secret knowledge as to why it's not so secret as it seems?

Also, many cultures believe in Satan they just use different names to describe it.

Worrying is important, ever hear that story.. "Hope for the best, but prepare for the worst"? It's a good saying! In order to prepare for the worst you have to worry about what could go wrong, this is called constructive pessimism and it is in my opinion one of the healthiest traits. it's basically why you don't walk out into traffic and get run over, cause you worry that would happen so you avoid it and you continue living.
