DC vs. Marvel Comics is the limited series crossover published by both DC and Marvel Comics that features a battle between Hulk vs Superman. It was published in 1996.
Other than fanfiction or speculative debates, I can't find an actual published crossover with Thor & Superman.
Superman debuted as the cover feature of the anthology Action Comics #1, cover-dated June 1938 and published on April 18, 1938
Superman was first published in October 1935 by the then upstart DC Comics. At this point, Superman was known as "Dr. Occult". The comic was first designed as a comic strip. When it caught on as "Action Comics", the creators of Superman changed it to a comic book form.

Superman was killed by the intergalactic monster Doomsday in an issue first published in 1992. But he did come back to life after four other characters had been introduced- Superboy (imperfect Superman clone)/ Eradicator (Kryptonian anti-hero)/ Steel (John Henry Irons in iron suit)/ Cyborg Superman (evil villain).

The word 'superhero' is merely a 'modernism' for what has historically been simply termed, "comic book heroes". As such, a crime-fighting adventurer does not have to literally have some "super" power to fit into the crime-fighting adventurer mould. This means that comic strips, such as Flash Gordon, The Phantom and 'Mandrake the Magician' existed well before Superman, for instance. Superman (1938), on the other hand, is called the "prototypical superhero" possessing or acquiring paranormal or parahuman powers, which makes him the first of the superheroes.
