"Angels" or whatever you want to call them taught us how to make weapons of war
there are more stars than grains of sand throughout every beach in the entire world added together lots of possibility to have other life
do you explain to ants why you build a house on top of their mound??? no most people see them as lower life forms and don't bother explaining it to them
why do we think ourselves so important we should be offered an explination or PROOF of all events that happen around us?
they have found gold jewelry that was a representation of a flying machine even w/ an accurate tail not found in nature.... do you think us primatives made it up?
we made a golden trinket w/ aerodynamics in mind before we had the wheel???
i also believe "stacking rocks" is a rather simplistic term when talking about the pyramids or ruins found in south america where stones that can't really be lifted easily today were moved and set in place and cut w/ more accuracy than we can produce today???
how did such simple creatures do this???
hey i dont see where the jump comes from
people can move rocks. with enough people people can move huge rocks. no one said it was easy for them im sure it was amazingly hard but they did it, same as building huge skyscrapers isnt easy but get enough people together and materials and you have one.
stonehenge, easter islands these are all just sites of worship or similar, look at what religious leaders have made followers do, cathedrals, the vatican and so many other things i cant think of since im wrecked.
when people say we have no explanation for them its that there is no evidence left after so long when all that was involved was people and maybe wood and rock, it is pre-historic times
also on hieroglyphs etc we interpret based on our experience and have an ability to recognise what we want. people look at the clouds and can see faces etc, these are all just inbuilt functions of our brain to help us function(relevant nowadays or not) recognise parents, dangers, social reasons etc.
im not saying there are no aliens i would think there is, as you say with something so huge as the universe but that is also part of it. the universe is unfathomably huge that unless they could master ftl travel it really wouldnt be worth their time to come here and stack rocks and have sex with some random ape hotty and so far as we know speed of light is the fastest anything can go. not saying we/anyone couldnt make a discovery but theres alot that says thats true.
just cause something isnt fully explained or seems a bit strange the default answer shouldnt be aliens, angels, bigfoot etc. there are mutations, even nowadays that cause rapid bone growth, gigantism, mishapen forms etc.
most of the "mysterious artifacts" that alot of stories come from could easily be faked how would you know that the "scientist/archeologist" doesnt have an alterior motive or is a fraud looking for money, a book deal or anything..
if you or anyone wanted to check research papers etc then that would be what id say to do not just watching youtube and tv because they are entertainment and are biased.
not meant to be aggressive btw but just what id say.
