Caesar was dabbing on someone in Gaul and someone stole the gold from Delphi and then moved to central Turkey Maybe calling them "Celts" is not accurate and perhaps they don't have much in common with the current day inhabitants of Ireland but these people definitely existed

except we have no evidence of them speaking a common language

We know for a fact there's no genetic link between them. Some say there's linguistic evidence, relying on the idea that Lusitanian languages are 'Celtic' - an unverifiable claim.

I think we need to distinguish between strong & weak arguments: Strong: the iron age inhabitants of Gaul were similar enough such that they appeared to be a similar culture to their outgroup and wandered around occaisonally Weak: these pepo also lived in Ireland and the UK

That "strong" argument is in fact weak. All the sources we have about so-called "Celts" are co-dependent and mostly derive from Herodotus. I've seen every single iteration of the word 'Celt' in Greek and Latin printed on five A4 pages, 95% are based on a single use...
