Is there any Evidence for Ancient Advanced Civilisations?Civilisations as we understand them are believed by mainstream archaeologists to have begun around 5000BC. However, is it possible that advanced civilisations existed before this time and we have yet to find any evidence or understand the evidence we already have?
To try to assess the information I've grouped items into 3 headings.
Facts Beyond DisputeSea levels are much higher now than 10,000 years ago
Much of the planet has a very different climate to 10,000 years ago
Gobekli Tepi was used around 12,000 years ago, possibly as much as 15,000
Pyramids of Giza are aligned to exact compass directions
Many species became extinct around 12000 years ago especially in North America
Method of building the Pyramids is unknown
Date of construction of Sphinx is unknown
Asteroid or comet impacts have occurred in the past

Disputed Theories from Extrapolated Data
Weathering on the Sphinx indicates it was built when water flowed. This would be at least 8000 years ago.
The Sphinx is aligned to the constellation Leo which implies building 10,000 years ago
The Pyramids of Giza are in scale to the circumference of the earth and this was planned by the builders
