I read through a chunk of timeline. On the canon issue at least the term "early" that you use elsewhere is necessary. But I also found a number of puzzlers.

1. Circumcision becomes a rite for marriage for whom? I don't see any context on the screen to tell me.

2. Moses gets saved from what? If from the river, I'd expect to see his birth. Otherwise, I don't have any good guesses - maybe from the Israelites in the desert when he ticks them off?

3. They were originally created as fragments! Its all in how one diagrams the sentence.

4. The Middle Copper Age has a duration of 1 year or less? I'm not convinced.
I can afford to be amused because I am not using them in a presentation. If it were otherwise I would certainly want to be prepared to give listeners a reasonable explanation of the entry ... for fear someone like me might be in the audience.
