I’m not sure if I worded my question correctly, but let me try to explain more.
If we use a giant telescope to look at another planet 10 light years away from us, we would be looking at how it was 10 years ago. The thing I don’t understand is how does light store and also transfer all the information about that planet (or all the “data” that ends up in our eyes) and yet it’s still the fastest thing.

Well light does not store data in a way a cargo ship stores cargo. We encode information in the light itself. The same way as when as kids we send signals with a flashlight. 3 short blinks mean come over. The light is just light and carrys no information in that sense. But because it bli ks 3 Times we can extract information from it.
