40,000 years is enough time for 5 iterations of civilization up to the atomic age and destroying themselves. There's plenty of room for your theory without science being wrong. And as far as I can tell, history books haven't been that wrong in a while. People claim, but have no proof.
evolution is a theory, not a fact
In the sciences, a scientific theory (also called an empirical theory) comprises a collection of concepts, including abstractions of observable phenomena expressed as quantifiable properties, together with rules (called scientific laws) that express relationships between observations of such concepts. A scientific theory is constructed to conform to available empirical data about such observations, and is put forth as a principle or body of principles for explaining a class of phenomena.
unless you have a time machine you cannot prove beyond any shadow of a doubt that intelligent beings were not here 200,000 years ago.

Incorrect. 200,000 years ago, humanity was one of several human species. We were barbarians living in caves. and we were NOT, I repeat, NOT psychologically the same.
Again, we call this Behavioral Modernity. It is a fact that our bodies are older than our minds. Behavioral Modernity is the time when we started using that intelligence like we do now. When the biochemistry of the mind, and the mind itself, evolved to open the keys to imagination and art and science. It is when the cave paintings began and when we started developing.
This was 50,000 years ago.
Humanity is 50,000 years old as we are now. 200,000 years ago we were busy killing Homo sapiens idaltu and Homo Erectus and various other groups. No society. We were still animals.

Modern man were the surviving members of a population bottleneck from an estimate of 90 to 70.000 years ago from a natural cataclysm that could have wiped us of the planet as it caused the population to drop to only an estimate of 2000 members. The eruption of lake Toba, a super volcano has been pointed at as probable cause of this event.
