Allah (ﷻ) Teaching Adam Billions of Names

From this verse, an argument may arise against the Quran, saying that Allah "must have taken a while" to teach Adam the names of everything in existence, making it seem like a logical absurdity:

And He taught Adam all the names, then showed them to the angels, saying: "Inform Me of the names of these, if ye are truthful."

2:31

However, there's absolutely no authority for anyone to make the process of learning sound so lenghty in time; if people cared enough to read some Tafsir books, they would note that Allah taught Adam the names by placing knowledge of them into his heart:

And He taught Adam the names, that is, the names of things named, all of them, by placing knowledge of them into his heart.

Tafsir al-Jalalayn (2:31)
