Yes Linux was written from scratch, so is Solaris or AIX or HP-UX or even *BSD. All of them are Unix! "
No, Solaris or AIX or HP-UX and even *BSD were not written from scratch. They all inherited an existing codebase that came before them, they are all "forks" of an earlier version of Unix. They are all Unix.
Only Linux, and the original Unix itself, were written from scratch.
Linux is not Unix. There is not one line of Unix source code in Linux. Linux was written from scratch, by Linus Torvalds.
Like so:

In this figure, solid lines entering from the left represent existing source code.
Do you understand now?
PS: BTW, the GNU/Linux OS uses GNU (and GNU was written from scratch, by Richard Stallman), but the Linux kernel itself does not use GNU, so the Linux kernel was also written from scratch. Android uses the Linux kernel, but it does not use GNU AFAIK.
GNU is also not Unix. In fact, the very abbreviation, GNU, satnds for GNU is Not Unix.

"GNU is a recursive acronym for "GNU's Not Unix!", chosen because GNU's design is Unix-like, but differs from Unix by being free software and containing no Unix code."
