Was There An Ancient Highly Developed Civilization?

I looked at several forum threads, and we have talked about various aspects of this possibility, from the ancient aliens theory, to pyramids all over the world, underwater lost cities, and strange earth formations that look like the stumps of gigantic trees.
We have talked about giants, lost technology, and pictures that look like spaceships. What I want to do in this thread, is just kind of bring all of the pieces together, and include anything that alludes to a lost advanced civilization.
I am hoping for input from @Sheldon Scott , @Joe Riley , @Patsy Faye , and I wish that @Terry Page was still around , because he has been so many places and could add so much personal observation about things he has seen in his travels, that points to an advanced civilization.
I am putting this here, and not under conspiracies, because we have pictures and evidence of this civilization, and we can discuss what it was, and how it might have come about.

Here is an interesting video that shows some of the ancient buildings that we are uncovering underneath other buildings that are old themselves. There are pictures of giants, petrified wood that looks for all the world like someone’s woodpile, and other intriguing pictures.

 

Sure looks like this guy is using a computer......

 

These do look like they could be some kind of astronaut , pilot, or space traveler. I think that the book about ancient astronauts has some amazing finds of our world that point to a higher civilization than we have been told for that time frame.
That these kinds of artifacts come from virtually all over the world has to mean that either many of the old cultures understood this, or that the civilization that did understand space travel went all over the world.

I am endlessly fascinated reading about possible high-functioning ancient civilizations, in America, and all over the world. When you look at pictures of these old buildings, or the ruins of them, they look amazingly alike , no matter where they were built, leading me to think that there could have been a world civilization at one time.

Anyway, one of the questions we ask ourselves, is why, if there were already old castles, buildings, and ruins already here when the first documented people settled in America, why is there no record of people finding these ancient buildings ?
Most of them are said to have been built in the 1800’s, when most people barely had wood and dirt homes to live in, and in contrast there are mansions that would take an expert craftsman to build and create the decorated walls and ceilings of these homes.

I watched a video tonight that shows an old newspaper from 1858, which talked about “ancient American antiquities”, and describes the beautiful buildings that were found by the first explorers to cross the country.
I am posting a copy of part of what the newspaper article says, which is reprinted so that it is easy to read; but the picture of the actual paper is in the video. I know not everyone wants to take the time to watch a video (this one is about 20 minutes long), but the newspaper article is easy to read.

 

Here is the video that the above article is from. This does not specifically mention Cahokia, but it seems to me like it would have to be related, so I believe this will really interest you, @Joe Riley .
If indeed these cities were built before the Christian Era, then they would have to be at least 2,000 years old, at the minimum, and maybe a lot older, since we know some places were already ruins before the Christian Era even began.

 

This is a temple that was buried and then discovered and unearthed in India. It is called Vettuvan Koil, and is from the 8th Century. The whole thing was carved from solid rock.
Some of these magnificent buildings can not even be duplicated today, with all of our modern equipment, and it makes you wonder where they found the skilled craftsmen that would have been needed to carve all of this ?
