Why do we see the same exact stars pretty much every night, if we're rotating around a big ass sun in a big ass solar system? What the fuck?

Because they are very far away from us.

We don't, stars change with the seasons and the rotation of the Earth.

Because Global Turning is just a scientist plot to make money.

Many constellations are somehow visible year round. Ursa Major, Ursa Minor, Draco, Cepheus, Cassiopeia, Camelopardalis...

That's because they are near the celestial poles.

Its actually a really interesting and complicated question. I highly doubt you understand all the nuances of it.

No one in this thread has answered shit.

It's clear that this is one of God's mysteries.

No it isn"t. We dont have "the same sky" every night.
Some stars dissapear and new ones appear. In reality, its just their 'light' that reached our earth.
Some stars we see in the sky might be dead already and others may exist that we dont see yet.

And that doesn't even begin to explain it. Nice job.

While we are rotating around the sun, yes, the sun s also rotating round the center of the galaxy, effectively making us stay in place.
Think of it as walking down an escalator that moving up, while rotating on yourself...

No no no, the sun is rotating around the earth. The earth always stays still.

it's just light from billions of years ago, they are most likely dead by now.

Barnard's Star has the fastest proper motion of
10.3 arcsec/yr. Over the span of about 50 years of your adult life, Barnard's Star will traverse about 500 arcsec, which is about 1/7th of a degree in the sky, which is about 1/200th of the visual diameter of the moon.
