MUFON vs. Stephen Greer
Format: Paperback
How it relates- this book was once sold (now out of stock) by mufon on their website- out of the many books that could've been chosen.
I see a lengthy review by an obvious Stephen Greer fan. I, too, have seen his films. I was also once a member of Mufon in which paying that membership fee allowed me the extra little bit of privilege to attend web seminars/ community zoom meetings.
I participated in some of these meetings to fully feel and understand what I was paying for, honestly.
I joined mufon as a Stephen Greer fan myself so I was excited to use the opportunity to ask others of their thoughts about him and his films during one of these meetings. What I got was silence and if anything, a slight scoff. He was quickly dismissed and I was left with my own conclusion.
This book is like most say- very interesting. I think both the author and Stephen Greer may have some things right but but all.
My first instinctive question about this book was "how does he know this?" Right out of the gate, I'm assuming it's pure sci-fi but he does provide some backstory.
Well, his work is comprised of others accounts.
It can be unnerving when it comes to the malevolent species.
If I had to pick a side drawn from my own conclusions- it would be MUFON over Dr. Greer because if there are malevolent species, you won't catch me in the open air shining lasers and telepathically calling the closest craft to come down and visit, blindly welcoming.
Some close encounters and abductees are horrified by their experience and live through a lasting trauma.
If you peruse the national ufo reporting center website, you will see reports of different crafts and behavior. One could interpret this as different levels of curiosity or.....various agendas.
The universe is infinite as far as we know- beyond our humanly knowledge and capabilities. We haven't even fully explored our own galaxy. If we have the ability to be malevolent at times, what human can really say there's not another life form like us? Another life form that relies on food (other life forms) for energy? We all know what can happen when we get a little hungry. We all know the greed that can came from the demand and price of natural resources. Could other species scout the Earth just as we are racing for resources on the moon? There should be no limit to possibilities so I can only stay open minded.
BOTTOM LINE- 100% would recommend as a read. It's different from the others when you want a refreshing change in format. No long stories so you can pick up anywhere- almanac style. A reference guide for alien races that can be quite entertaining!
