Here's why:
* The Basque language and culture are distinct from Celtic languages and cultures found in Ireland.
* There is no archeological or linguistic evidence of a Basque presence in Ireland.
* The earliest confirmed human settlements in Ireland date back to the Mesolithic period (around 8000 BC), long before any known Basque migrations.
While the Basque people have a rich history and culture, there is no historical basis for the claim that they discovered Ireland.
