Anthropologists believe the beginning of all spoken languages began in several thousand years ago.?

That's not quite right. Anthropologists believe the beginning of all spoken languages goes back much further than several thousand years.

Here's what we know:

* Origins of language are unclear: There's no definitive answer on when language first emerged.

* Estimates range widely: Some experts believe it could be as far back as 100,000 to 200,000 years ago, based on evidence from brain size, tool use, and potential vocalization abilities of early hominids.

* No concrete evidence: The earliest written records only date back a few thousand years. We don't have direct physical evidence of spoken language from those earlier periods.

So, while we can't pinpoint an exact date, it's generally accepted that the origins of spoken language predate the past few thousand years.
