Because water is SPECIFIED to be #H_2O#, i.e. oxygen in the #O(-II)# state......

Explanation:

And clearly this atomic composition can be verified experimentally.

If you have #H-O-O-H#, we gots oxygen in the #stackrel(-I)O# state....the #O-O# bond is relatively weak, and its length is #1.474xx10^-10*m#.
