Proto-Indo-European: A real language or a remnant of Babel?

From what I understand, Proto-Indo-European (PIE) is just a hypothetical construct — hypothetical because no writings in PIE exist and no scripts are known that were used to write it. PIE is reconstructed based on its supposed daughter languages.

My question is whether some of the hypothetical daughter language groups — Proto-Germanic, Anatolian, Romance, Celtic, etc., might actually be remnants of the breakup at Babel around 2,000 BCE. How that breakup looked at the time is not specified in the Bible account.

PIE might have been one of the languages that emerged from the confusion. Then its speakers might have migrated north into Anatolia, the Caucasus, Eastern Europe, Western Asia, etc.

Or PIE might just represent similarities among various split-up language groups that came out of the confusion.

Just thinking out loud.
