Sorry but the sources you linked to are full of easily debunked fringe archeology. They have been discussed on here ad nauseum over the years - search
is your friend if you wish to find out more.
Ancient humans had the same brains we have - they were just as clever as us. However, they didn't take things far enough for serious technological
advancement. For example, Hero developed a steam engine (aeolipile) somewhere between 10 - 70AD. However, whilst it was an extraordinary bout of
scientific achievement, it could only be made in small scale and it didn't work for long, basically because manufacturing and refining techniques
were sufficiently advanced to make cast iron or steel that could withstand the pressures generated (pipes cracked).
The most extraordinary ancient artifact is the Antikythera Mechanism. The sophistication and skill required to both develop such machinery and then to
achieve such extraordinary accuracy for its astronomical accuracy wasn't matched until the 19th century. There are a myriad of reasons why such
technology never developed - war, death and destruction being just some of them.
Basically, you are free to believe whatever you desire - it is entirely your choice. For me though, i will stick to verifiable facts. For me, fringe
archeology is interesting in that it opens up the realm of "what if's". Until science can verify some of the claims though, they always remain
"what if's" rather than fact.
