These things should be everywhere, but unfortunately we don't see them anywhere.

There's actually quite a few pictures out there from around the universe if you look, there's even been footage captured of what looks like a huge ship pulling energy from our own sun. I would suggest you have to look at conspiracy sources though as NASA nor any other established governmental authority on the subject will likely ever show us this information in an honest manner until they secret is out.

Furthermore I would say that it would be helpful to stop expecting aliens to behave like us. Maybe they don't need any of the stuff we need and are totally beyond all of our expectations. Maybe they are even in another dimension as well so that traditional visual approaches would not work.

But honestly its not that weird that an ancient civilization might look at comets and think "vehicle of the gods". Almost all civilizations have also reported visitings by ghosts and other creepy things.

That's certainly possible that they sort of anthropomorphized natural phenomena like comets and meteors and such, though.. To me the more I study it I think they had visitations from beings. Ever heard of the Cargo Cults? I think something similar going way back in history is very likely.

Mass sightings are weird, but they are almost entirely UFO sightings which could have a number of natural causes. It should also be considered that unless there is multiple sources for a mass sighting there's a pretty reasonable chance that it wasn't a mass sighting at all.

Many of the testimonials report interactions with actual beings, very detailed in how they look and the beings vary of all different kinds from reptilian types to small little humans to greys to on and on and on.. These also extend to highly credible people who work within government and militaries as well who leak out information they claim they were not suppose to.

Which works on the concept that given an infinite amount of time anything that can happen will happen. For example perfect recreations of you complete will all your memories.

I've heard that theory before as well and I'm open minded to it but also skeptical especially if there is no such thing as time in a more than psychological sense.

Complete with its own civilization(s). This leaves the interesting question of "what is it the people and matter in your dreams are made of". The most logical answer I can think of is they are made up of consciousness.

Interesting thoughts indeed. I tend to agree and think they are all part of the "one consciousness" and that we're all just different expressions of that whether awake or when dreaming.

That is the crux of it, in the end there is nothing that we can truly know beyond a shadow of a doubt.

Hmmm.. I sort of agree. It's a deep philosophical subject and the incompleteness theorums really opened my mind in regards to that, but on the other hand I'm not convinced it's true either, maybe we can know some things. I can't say for sure but it seems like a good thing I can say that I know is.. My own name..Or if I give a name to an animal or a friend or whatever.. I can know that that name is associated with them through my own association of such. However.. I guess the caveat is that.. Maybe nothing is real and it's all an illusion, if so.. Maybe it's true that we can't know anything.. I'm not sure, lol!
Thanks for the interesting conversation. :)
