I think the thing is that in our past lives we had a lot more time to do nothing. Have you ever sat and stared into a fire for an extended period of time? These kinds of calm moments of reflection happened far more often in times gone past, especially for tens of thousands of years before significant we developed civilisation.
Presumably because this time was abuntantly available, evolution found ways to do some kind of bookkeeping that is very important for our survival, in a similar manner to why sleep is important.
This is of course speculation, but in the absence of definative research about the human brain, which is a ways off just yet, this is almost the best we have.
