Because you can't have G and Gb in the same scale. The note names come from the progression A, B, C, D, E, F, G and you have to have one (and only one) member of each of those note name groups to properly name the notes of a Major scale.
That way we can make sense of all the enharmonic equivalents you come by in the 15 different key signatures (C Major, plus 7 sharp keys and 7 flat keys).

How many key signatures exist?
15 different key signatures exist. (no sharps or flats) = C major F sharp= G major F C sharp = D major F C G sharp = A major F C G D sharp = E major F C G D A sharp = B major F C G D A E sharp = F # major F C G D A E B sharp = C# major B E A D G C F flat = C flat major B E A D G C flat = G flat major B E A D G flat = D flat major B E A D flat = A flat major B E A flat =E flat major B E flat =B flat major B flat = F major
What are accidental signs?
An accidental can be a flat, natural, or sharp, used for a note NOT in the key (such as an F-sharp in C major).
What is key signature mean in music?
What is a key signature? A key signature is the number of sharps or flats in a piece of music. For example C Major has no sharps G Major has 1 Sharp F Major has 1 Flat B flat
What are the sharps in the key of A major?
it depends on what key its in. Theres not specific sharps for the bass cleff, it changes according to the key just like treble. If your in the key of c, then theres none. If your in the key of G, then theres one sharp (Fsharp)... etc etc.
How many sharps are in the key of f sharp?
None, only flats. B flat in F major, B, E, A, and D flat in F minor.
What is the key signature for D sharp minor?
The key signature for D sharp minor would be the one for F sharp major: FCGDAE. You can also think of it as E flat minorwhich is related to g flat major in which the key signature would be BEADGC.
Which key has 6 flats?
The key with 6 flats is G flat major (this is the same as the key with 6 sharps: F sharp major). The relative minor is e flat minor (also called d sharp minor).
What key signature has g sharp f sharp and d sharp have?
The key with three sharps is A major, however A major uses C sharp - alongside with G sharp and F sharp - instead of D sharp.
How many key signatures exist?

(no sharps or flats) = C major F sharp= G major F C sharp = D major F C G sharp = A major F C G D sharp = E major F C G D A sharp = B major F C G D A E sharp = F # major F C G D A E B sharp = C# major B E A D G C F flat = C flat major B E A D G C flat = G flat major B E A D G flat = D flat major B E A D flat = A flat major B E A flat =E flat major B E flat =B flat major B flat = F major
What is the key signature for a D scale?
D major has a key signature of F sharp and C sharp D minor has a key signature of B flat

What is the principle or the rules in finding the key signature?
TO FIND THE KEY FROM THE KEY SIGNATUREIf the key signature has sharps:The major key is the note above the last sharp in the key signature.The minor key is the note below the last sharp in the key signature.Ex: key signature with sharps f-c-g is A major or F-sharp majorIf the key signature has flats:The major key is the note of the next to last flat in the key signature. If there is only one flat, it is F major.The minor key is the note TWO notes above the last flat in the key signature.Ex: key signature with the flats b-e-a-d-g is D-flat major or B-flat minorIf the key signature has no flats or sharps:The major key is C.The minor key is A.TO CREATE THE KEY SIGNATURE FROM THE KEYThe sharps always go in this order: F-C-G-D-A-E-B-C (circle of fifths)If you are creating the key signature for a major key, keep writing sharps until the last sharp is the note below the key you need.If you are creating the key signature for a minor key, keep writing sharps until the last sharp is the note above the key you need.Ex: The key signature for B major and G-sharp minor is f-c-g-d-a.The flats always go in this order: B-E-A-D-G-C-F (circle of fourths)If you are creating the key signature for a major key, keep writing flats until the next-to-last flat is the key you need.If you are creating the key signature for a minor key, keep writing flats until the last flat is TWO notes below the key you need.Ex: The key signature for E-flat major and C minor is b-e-a.The key signature for C major and A minor has no flats or sharps.The key signature for F major and d minor has ONE flat (B-flat).
Why do keys do keys have the same pitch but different key signatures?
There are three keys which are called "enharmonic keys", the three enharmonically equivalent key signatures are B major/C-flat major, F-sharp major/G-flat major, and C-sharp major/D-flat major and likewise their relative minors. B/C-flat, F-sharp/G-flat and C-sharp/D-flat all share the same pitch but are just notated in two different ways. In an other way the keys mentioned above are just one key going by two different names but they use different accidentals and are written on different lines/spaces.
How many sharps are in the key of f sharp?
None, only flats. B flat in F major, B, E, A, and D flat in F minor.
