“If it is real and an alien species has the technology to traverse the vast distances to visit or study this planet, there is zero possibility we would have the technology to defend against them.”
They have already been here for thousands of years, and no we do not have the technology. Oddly, they have not yet made themselves a real threat and just hang out on the sidelines.
Yep. We have nothing of physical value for ETs that have learned to instantly transit space-time. The concept of conquest/killing is of lesser minds stuck in one limited place.
They may watch us for ideas to bring to their own civilizations. Possibly even taking in specimens to study. Like when we closely study animals for inspiration to create better machines and software.
I also think they watch emerging civilizations and do interfere when technology can disrupt their own timeline. Things like nukes and particle colliders may have effects on space-time we still know nothing about. Sort of like watching primitive civilizations that are just discovering fire but without any knowledge of how much damage it can do if not controlled...
Oddly, they have not yet made themselves a real threat and just hang out on the sidelines.
They were here last Thanksgiving and radioed head quarters and reported what they observed first they made a cadaver head out of a pumpkin and put a candle in it then now there pushing bread up a turkeys ass over and out.
