When adam named all the animals?
The ‘naming’ narrative has a deeper meaning than actually assigning names to every species. In Hebrew, to name something is to symbolize having authority. God named Adam. God changed Abram’s name to Abraham, etc. In the narrative, God gives Adam authority over creation. This is why He instructs Adam to “have dominion over it”. This is symbolized by Adam naming (having authority over) the animals. More importantly, the explicit focus of the naming narrative is for Adam to discover that God has not yet made a partner compatible with him. Adam names the animals by kind, and then realizes that there is not a partner suitable for him. After this self-discovery, God acknowledges Adam by then creating a partner for him. Whom Adam then names. Now, as for what language Adam spoke. I doubt it matters.
