if we read carefully, MN 60 states this right view is that of "existence"

What does "existence", or a "doctrine of existence", refer to here?

this can be contrasted with SN 12.15, which states the view of existence is not right view. the right view described in MN 60 is the same as the defiled right view described in MN 117. thus I recommend to study MN 60, MN 117 and SN 12.15.

Now I'm confused!
