To sum it up.
You brought a few shittos that perhaps some of the science that Chazal wrote in Aggadita was based on the science of their time.
However as I indicated Slifkin’s approach encompass’s many aspects the sum tota of which have no source at all and actually have been condemned through out the ages.
You did not bring a single source supporting Slifkin’s approach to Aggadita or to Gemara.
Like I said you cannot bring any because they do not exist.
