"No spontaneously reborn beings"

One of the 10 wrong views is the view that there are no spontaneously reborn beings. The preceding 2 wrong views in the sequence of 10 are "there is no mother" and "there is no father". 1. Now beings born on earth mostly see beings coming to existence due to a mother and father. Most will never see a "spontaneously reborn being". So how does one form the view that there ARE spontaneously reborn beings when one has never seen such beings? Or is it adequate to simply not reject the possibility of the existence of such beings, but not form the view that there are such beings? 2. Also, if one has the view that there is a mother and father, how does one reconcile these 2 views with the view that there are spontaneously reborn beings, which we are also told are born without a mother and father? Further, say if all the beings we encounter were born spontaneously, how can we form the view that there is a mother and father? Or do the words mother and father mean something other than the biological parents or the first pair of primary carers, e.g. DP verse 294? 3. Why is this view included in the 10 wrong views? The other 9 views does provide a framework for beings to avoid evil and do good. Rejecting this wrong view and accepting its opposing view that there indeed ARE spontaneously reborn beings requires a stretch of the imagination for many. What is the moral purpose? Once again these questions are asked only for academic interest.
