No sir

I reject the assumption

It's much less of a logical leap to assume that at one point we simply had greater technological skills which we later lost due to some great societal or climatory shift.

Booking marking for later even though I think these shows are kings of at stretching truth

Watch it by the link I give in the OP, not by that puma punku video.

It's divided in 9 parts, after seeing the first you may look after "parte 2 de 9" and then "parte 3 de 9" and so on.

That's an upload from a portuguese dude

So you can find dinosaur skeletons and other artifacts "lost" in various situations but you cannot find "the lost human tech"

that's very selective don't you think? You just brought the same point as a friend of mine was bringing while watching this documentary with me and as we get more deep into that documentary that point would make less and less sense.

....Are you familiar with the Plea to Ignorance? It's a logical fallacy where, when applied to the creation debate, is often used as a (fallacious) proof of God: "I cannnot think of any other means by which this would have happened, therefore God must have done it." It's also called the fallacy of personal incredulity (I think). It can be applied in a lot of ways.

Using that same reasoning to arrive at the aliens conclusion is just as fallacious, and takes an enormously longer leap in logic to arrive at.

Yes, it is just more reasonable to assume that we had techniques, in the ancient past, that we have simply lost. Hell, believing that some terrifying civilization spent a thousand years building that place makes more sense than aliens.

I think with a lot of people and with a lot of time such things can be explained.

This is exactly what I'm thinking. Imaging a dynastic cult that ruled over thousand or millions of people for a century or more, an entire country toiling as one for years and eyars and years and years...

Hard to imagine, isn't it? But on a smaller scale, it could make sense (while still being awesome and also horrifying)

I thought this whole thread was about lost human tech which has been found?

And I'm not proposing that people simply had our technology 5000 years ago. They had their own technology, which we may or may not have rediscovered. Easter Island, Stonehenge, and the Pyramids were once thought to be impossible for ancient civilizations to build, but it turns out that they had simply developed clever tools and techniques which had been lost to time for one reason or another. They used techniques which we simply wouldn't bother with nowadays because other solutions are open to us. Almost no construction these days even bothers with quarrying, so it's no small wonder that a civilization without concrete might be more clever with stonework than one which prefers to pour its own rock.

@ khuutra

I'm not stating that just because there's no proof of what happened, there's gotta be god or aliens or whatever.

I'm just saying that such an explanation is as plausible, because to date, there's no proof of an ancient ultra advanced civilization, yet you got many material about this alien theory.

Have you watch the documentary just for instance?

I just recalled now, in that same documentary there's a part where scientists talk about a map that was discovered some years ago.

 it's a map from medieval days (1500 AC more or less) were it shows the south pole and south America with accurate detail that rivals Nasa satellite's.

How was such a map made in those days I don't know, but I don't think they just jumped onto a boat, removed all the ice from Anctartida to see were land was taking place.
