Within math, they sorta exist (allbeit in undefined ways). In reality, they don't. I'm talking about reality here.

No, it can quasi-mathematically exist. In reality, it is meaningless.

No. It is obvious that I'm perceiving something of the subset called time. Past is irrelevant. Future is irrelevant. It's all continuous. Where would you make a distinction on a circle as to what is "past" Wade?

I'll concede this. I actually was thinking of a line segment when I wrote this.

It does bring up an interesting point about the notion of time "lines" however.
