I'm mentioned? lol
Here are some reasons I theorize that The Minish Cap is first:

- In the Minish Cap we learn that the Light Force is housed in Zelda, and that it has been
passed down from princess to princess. This could be the explanation for Zelda's mystical
powers in every Zelda game, implying that MC is very early in the timeline.

- WW Link's Shield is a relic from pre-flood Hyrule. It is said to have been used
by an earlier Hero. We know this is not
OoT Link's Shield. It couldn't be. This
shield has been passed down in WW Link's family, and WW Link has no connection
to the legendary one (
OoT Link).
I believe that WW Link's shield used to belong to MC Link, kept as a memento
(a gift from Princess Zelda); both the vendor in The Minish Cap and
Wind Waker's Tetra poke fun at the small size of the shield.
Here I have posted
quote evidence which goes into this topic in some detail.
Theorists who place The Minish Cap after WW face the problem that a new
culture is manufacturing shields whose design is a relic from the past...

- Daphnes is from an age gone by, before Hyrule was sealed under the Great Sea.
Daphnes dresses like Daltus does. Considering the massive culture shift in Wind Waker,
I doubt that Daphnes' style of dress continues into the new world. More likely Daphnes
is dressing in the tradition passed down by the pre-flood Kings of Hyrule.

- The Hero of Men legend appears to be mankind's first encounter with the Picori.
The Picori are given credit for items hidden in pots, grass, and bushes. This means
that the Hero of Men legend would predate every game with items hidden in pots, etc.

- In
ALttP, the Pegasus Boots are a relic from the Hylian age, yet they are commonly
manufactured in The Minish Cap. MC after WW or
ALttP is unlikely, as both
games are distanced from the Hylian age.

- The same japanese word is used for Force Gems and Light Force.
I think the Hero of Men legend (which introduced the Light Force)
must predate any game with Force Gems in it.

- Phantom Hourglass has Force Gems. Since Force Gems and the Light Force
seem to be the same form of energy, I conclude that Force Gems did not exist
until after mankind was given the Light Force. Of course this means that the
Hero of Men can't be after
PH, so it must be before. Since there are no Heroes
between
OoT and WW/
PH, the Hero of Men must predate
OoT.

- Some theorists try to throw you for a loop by pointing out that in several
Zelda games, Link begins the game without a cap (implying that the cap
is not an important timeline connection). What they leave out, of course,
is the fact that The Minish Cap is the
only game in the series in which
Link
wears the Hero's Clothes without a cap. In every other instance, Link
receives a cap along with the clothes
as a part of the standard Hero uniform.
Some of these reasons may be subtle, but that's a long list of things to ignore...
