The problem with debunking the stoned ape is... many people have taken magic mushrooms and have come back with information that they didn't have before.

Wherefor was this information gained?
It happens too often to be a just an accident.

The next problem is the "stone age"

We are the 13th advanced civilization on earth.
Until we stop thinking that we are the most intelligent form of mankind ever, we will just keep coming up with stupid theories.

There are too many objects on this planet that we can't produce today. Both large and small objects. Objects that shouldn't exist if we are the pinnacle of advancement.

There are too many stories and signs that they were true that tell of ancient advanced civilizations.

So, taking that into account, our entire time line is seriously messed up.

And the idea that we evolved from apes either means we have no idea about evolution, or that we are just that colossally stupid.
