I started removing the wet sheetrock around my skylight to try and
find out exactly where the leak is coming from. I found the leak
coming from the bottom 2 corners of the skylight. It might be hard to
see in the pics, but there is an opening in the corner with what
appears to be some yellow caulking inside.

I confirmed this by spraying a garden hose on the roof on the bottom
corners of the glass, and my son inside confirmed the leak was coming
from those 2 gaps in the corners.

So my question is, what are these 2 openings for? I would like to fix
the leak before I go ahead and finish the sheetrock. I thought about
maybe caulking those 2 openings on the inside, but it is obvious the
leak is coming from the outside on the glass. Can the seals be
replaced? It is at least 20 years old.

That skylight looks awful flush to roof surface, where driven rain or
ice dams in winter would get up under it. I wish you had included an
establishing shot of the entire skylight from outside, with something in
picture to show the scale.

At 20 years, I'd bite the bullet and replace the whole damn thing,
including any mushy wood. I'd also reconstruct it so the skylight bubble
and gaskets were 6-8 inches above roof surface, so water could never
pond against them. I'm no expert, but I understand they now have prefabs
that go on as easy as a roof vent, and all you have to do is figure out
how to make the tunnel up to them. BTW, regular drywall is a poor choice
for the tunnel, in case of any condensation or similar issues. *The
fancy bathroom drywall, or even heavily sealed plywood (like on a boat)
will hold up a lot better.

Here are some pics from the outside taken about a year ago.

And yes, those are the old roof shingles its resting on.When the
previous owner wanted a new roof, he also added thses skylights, so
he, or the contractor, cut a hole in the roof and just rested the
skylight on the old shingles, and put the new ones around it.
