If you think about it, our planets were made from the ashes of a nebula, which is a dead star. But that took hundreds of years. Will our sun burn out too, or do I just need to find a hobby?

The sun will turn into a red giant, then into a white dwarf surrounded by a planetary nebula. This will take billions of years. The white dwarf is basically the ash of a star. It’s a hot glowing remnant that no longer has nuclear fusion and so it’ll just glow for trillions of years slowly losing heat and light until it becomes a cold lump of carbon. The inner solar system will most likely be wiped out during the red giant phase as the sun will expand tremendously in size eventually reaching somewhere between earth and mars’ orbit.
Fun fact, while the earth will almost certainly be engulfed by the red giant phase of our sun, it will not be immediately consumed. A floating lump of rock will exist and continue to orbit the center of mass for millions of years inside the sun.
A problem i see with your theory is that the outer layers of the sun are plenty hot enough to melt rock and as soon as that happens the rock is probably just going to become part of the plasma making up the sun’s atmosphere.
That’s only true to the current outer layer of the sun.
Now consider that the sun will expand from its current ~1.4Mkm diameter to anywhere between 1.2 to 2 AU (1 AU being the distance between the sun and the Earth on average, so about 150Mkm). That’s a 200 times increase in radius/diameter, resulting in a drop of the surface temperature to around 2400K, which, while isn’t ideal for life (and in fact arguably the coronal plasma itself would be a bigger issue for life et al), is also not something the planet couldn’t withstand for a good while. After all we’re talking about a measly 2000 degrees Celsius or so.
