I tried looking it up, and my brain just wasn’t making sense of it, but I haven’t had coffee yet so.

Analog signal can have any value and digital, if binary, can have only two 1 or 0(true or false).
Why digital is better? Because the signal has less distortion and can have better error correction implementation.
How you ask? Imagine a bottle of water, full is 1 and empty is 0. Let’s say I have a full bottle of water(a 1), now I will add a distortion in it, so I’ll drink 1/4 of the water, in the end the bottle has 3/4 or more than half of it’s content, a computer will still interpret it as if it were a full bottle even though it’s not. Which is not true for analog signal, the analog will interpret the imperfection.
