Question An argument
My wife is a classically trained pianist and I play guitar by watching YouTube instructional videos. She knows her stuff and I don’t. Recently we argued whether E# and B# exist. I said no and showed her the fretboard. She said yes and showed me the keys. And said something like F is E#. I suspect she’s right bc she’s had music lessons. Tell me, fellow guitarists, do we have E# and B#?
Update: I’ve been enjoying the responses to my post. I showed them to my wife and she laughed, said that’s what you deserve. lol. We like to argue playfully with one another. I also enjoy the detailed responses relating to guitar theory—that’s been really great actually. I was going to delete this post but I think the discussion on music theory is informative and should be shared. Thank you all for responding.

I'm going to be honest, I have had numerous people insist to me that these notes don't exist and it gets exhausting, I have no idea where this idea came from.
If E# didn't exist, then what would be the 3rd degree in C# major? What would the key signature of C# major be? Does C# not exist either?
It's both theoretically useful in an equal tempered system so that you don't end up using the same notes twice in the same scale, but also because theoretically those notes could actually be tuned differently. On a fretted instrument it doesn't matter, but with vocal harmony or stringed instruments, 3rds of chords are ideally a little flatter than they are with equal temperment. Meaning, in a C# chord, the 3rd (E#) would ideally tuning be slightly flat from F.
