How do you know if something is really what it is cause it could really be called something else?

Oohh you are skirting around the edges of what philosophers call epistemology, the idea that asks whether it is possible to know anything.

Plato in his vast repertoire questioned, like you, how we know something exists. It is a bit clunky and hard to read but imagine you are sitting at a brown desk. If you turn off the lights is it not brown anymore, as you see it?

What makes a dog a dog? It is furry and has four legs. What if it loses a leg? Is it a dog?

What about an old car. You have had it fixed, parts replaced over the years to the extent that not one piece of that car is original. Is it the same car?

Plato had the idea that things exist as ideal forms and that all else was a shadowy copy of these forms.

Rather than bamboozle you here, go and read some Plato or some secondary texts and be prepared for an interesting ride.

Have fun

That depends on whether or not you think every inanimate object should have a name. The words we use to refer to objects aren't their names they are just words that refer to that object - they are Nouns.
