What does this mean then?

When I repeatedly said that these were the beliefs of most anthropologists and paleontologists and then you said the above, I can only conclude you assume most people in those fields don’t know what they are talking about.

Edit: This is the beginning part of the paragraph that you highlighted:

The conclusions (which aren’t MY conclusions) but are rather the conclusions of most anthropologists and paleontologists, and other subject matter experts were merely synthesized by me from myriad books and papers on these topics from a wide variety of related academic areas. You either don’t believe that since you’re acting like I just invented these concepts or don’t believe these experts understand their own subject matter — and you know better. 🙄
