1. Sounds like a reasonable conclusion, so no problem here.
2. "Rewind" is a bit of a difficulty for me here. Anytime you extrapolate information, especially over long periods of time, it makes it unlucky that you'll get a clear result that can be considered conclusive. One major anomaly or many smaller interference(s) including mild changes in conditions can dramatically change what actually was, compared to what we consider as likely. Can you maybe expand on the idea of "rewind" and how they were able to rewind to a single point with certainty. Also, I'm just asking out of curiosity so don't take it as more than that.
Because no matter in which direction the Cosmologists look everything is expanding away from everything else.
So 'Shrinking' everything puts it all back to/at 'Point 0'.
At the scales they are talking about... those 'Small anomalies'? They work out to evidence themselves as HUGE developments that we see in the stars/galaxies around us.
Here's the firstt, quick, Google-foo link to one such anomalous 'space'... uhm.. out in, well, space...

A great big place of... nothing.
So, yah, I agree there are/should be anomalies and... well... they're finding them.
So, that's a simple version of why things all came from a 'Big expansion'. Things were a LOT closer together... And not they aren't.
Not at work.
