What’s your best guess? Who are they and why... why here?
Gut response...Something external to man has been involved with us as far back as our records go. Whatever it is does not seem to want to destroy us because it certainly could.
It has the ability to exist as a material presence, yet also has the ability to defy all of the laws of physics we have learned ... so far.
I believe some individuals have interacted with it at a personal level. There appears to be either multiple entities or multiple “personalities” if it is only one entity.
For religious individuals, God, Angels, devils, demons, would qualify. For non-religious individuals, alien races seems to work. Even up for consideration is we are expressions of a virtual reality.
Regardless....SOMETHING is out there. I think it is alien and it doesn’t interfere with my religious beliefs, in fact in some ways, it seems to support them.
NOW...what do you think?
