PIE was the language (or languages) the proto-indo-European peoples spoke during their processes of migration into Europe, the Middle East and South Asia (around 6-4k years ago).
So most of the languages from those regions, from Hindi, to Persian, to Greek and English are all PIE, as these are all descendants from the PIE peoples.
We can reconstruct it by analysing these modern languages, their recent ancestors etc. and compare them.
But is it a language? I only know of Proto Germanic and Proto Indo-European that would be relevant here but I’m not a linguist.

I know. However I was wondering what proto European was supposed to be.
Those would be the PIE that entered Europe, so after they split from the PIE that entered Iran and India (the Indo-Iranians).
No, it’s a category, and the two languages you mentioned would, I assume, fit into that category.
That makes sense somewhat, although it would be a rather broad category.
