Same issue you're always going to encounter with scientists concerning aliens, UFOs and their collective problematic view of the realistic probabilities of UFOs, it's that they all encompassed inside their own brains, their own work, their own bubbles, they largely have a disdain for pop news media, or fringey topics, now add ego and the arrogance they display when when challenged by the notion that brainy aliens have been here, or are still here, but these science guys don't know about it? ...or they specifically are not in on the 'specifically cool people only' club of being aloud to have direct info and or access. So, point being, they are in their own select, self segregated bubbles and don't want to made to look outsmarted, or left behind, or out of touch, or caught in a potentially other embarrassing situation of being bamboozled by some sort of big CIA program to fool everyone. This is why it's so excruciatingly painful when these incredibly smart, well studied people seem to have very low value or maybe just low value of anything really juicy, interesting, or dramatic, or enlightening to add to the conversation about the reality of UFOs and ETs already being here. This is my take on this whole other interesting side study of Scientists and their lack of value based knowledge and or maybe just public opinions that they are actually willing to admit publicly," without fear of losing that next big grant or <a href=""http://govt.money/"">govt.money</a> disbursement. Maybe they do want to say more because they believe more but have to remain cautious and carefully tight lipped", out of fear.
