Why does time only move forward and not backwards?

You did that not me

Yes, for your original statement, which later on I assume you realized its falsity: in reversed time, circles go inward (to a decreasing and not increasing entropy), while you said always outwards ... . Simple.

The original statement was and is correct.

Edit to add... Your objection appears to have been that there is only one correct labeling for past and future. My suggestion is that if we are to give meaning to the notion of "time flowing into the future", one approach is to note that the labeling is arbitrary.

However, as we both agree, operationally the result is the same. The observable progression for inhabitants of a time-reversed universe is indistinguishable from that for a time-normal universe. Time still "flows" from the direction of low entropy to high entropy.

We both agree that one might as well label the direction of low entropy as "past". It would appear that our disagreement is purely about words and not about physics. However, I dislike to see "proven false" applied to a disagreement about words.

It's not just about words.

Time still "flows" from the direction of low entropy to high entropy.

Is incorrect, if you switch "past" and "future". Just make yourself a simple diagram and think carefully.
