UFO - ( Unidentified Flying Objects) , in Vietnamese it is Vật Thể (Object) Bay (Flying) Không Xác Định (Unidentified) . We can see that for a group of noun like this (idk what that's called) in VNmese is backwards for English. Hahah!
Why is it các and not những?
You can use những too, các is more formal.
Sounds like he is saying 'Cá vật thể'.
Pointless as its a sentence for objects such as planets etc!
