Whether our leaders have or have not met with aliens does not matter that much with me. I am sure that if some have met with these aliens my question would be more to what advances in travel and space exploration can they share with us. Maybe if they are meeting with people on earth then maybe they are meeting with the wrong people.
Myself, though out history, there has been tales of strange encounters. I once remember reading a book that compared the tales of the fae or fair folk with that of aliens and surprisingly a lot a parallels were drawn.
*Among both, there are many stories of those who ahd been kidnapped or abducted.
*Both tales of the fae and of aliens offer consideration of them being of small stature.
*There is an interesting correlation between that of flying chariots and spacecrafts which can be very similar.
*In many instances these encounters left people with pronounced changes both physically and mentally.
*Both had examples of lost memories and altered time, even having aged or found days, months, or years seemingly lost.
Really, I don't have any doubt that there is a correlation. Especially when you do some digging and compare what has been recorded.
I don't think anyone on this planet has met aliens. There is a definite possibility that there is life out there besides on our planet. No proof has been presented yet. It is all just speculations and conspiracy theories at this point. I will believe it when I see aliens landing on Earth. If that happens I do certainly hope they are friendly.
I think there is a lot of evidence that has been around that proves that more than once we have been visited by strangers. Whether or not that is from actual aliens or not is something yet to be seen
I would like to know more about some of the recent discoveries from the universe that we have seen.
