OK, so the star trails stuff is also pretty silly.
24:44 Asserts that the galaxy is moving at 670 million mph. No sources given.
https://en.wikipedia.org/wiki/Cosmic_microwave_background#CMBR_dipole_anisotropyThe milky way is moving at 627 km/s, which is only 1.4 million mph, so he's off by 2 orders of magnitude
Asserted: Sundials are still accurate after centuries. What? Of course they are. Noon is noon, how could it be anything else?
Asserted: Star charts are all the same throughout history.
This is only because history is so short and human lives are so short.
Stars that are closer to earth have easily observable proper motion, for example Barnard's star:

You need to consider timescales about 100 times longer than humans have been painting on cave walls:
https://www.wired.com/2015/03/gifs-show-constellations-transforming-150000-years/26:16 - he asks how a star that is super far away could stay still given all the motion. The farther away something is, the LESS its apparent motion. How is this not obvious to him?
26:30 - claims without any support that Polaris is visble from as far south as 20 degrees south latitude. This is simply not true.
Here are some pictures of star trails taken from Ecuador, 0 degree latitude. We know Polaris is right at the middle of the swirly part to the north, which is exactly on the horizon.
Find me a single picture of Polaris taken from the southern hemisphere.
http://sguisard.astrosurf.com/Pagim/From_pole_to_pole.html27:00 claims Ursa Major "right next to polaris" is visible from the southern hemisphere, shows a picture of Ursa Major from the NOrthern Hemisphere.
Of COURSE Ursa Major is visible from the southern hemisphere - it only goes to about 63 degrees north "celestial latitude" if you want to think of it that way, so you'd see it.
https://upload.wikimedia.org/wikipedia/commons/c/c7/North_Hemisphere.pngThis also means that "right next to Polaris" is like 27 degrees away. That's HUGE!
He claims Ursa Major is visible to 30 degrees south, and since it's close to 30 degrees away from Polaris this puts the lie to the notion that Polaris is visible at all.
27:10 Vulpecula can be seen down to 55 degrees south! Well, yeah, it's only at 25 degrees north or so. The sky is 180 degrees across, if your latitude is within roughly 90 degrees of a star you can see it if the time of year is right.
27:15 "Taurus, Pisces and Leo" are all signs of the zodiac. These are zodiacal signs because the ecliptic (where the sun goes) passes through them. This means that they are all within 23 degrees of the celestial equator.
All of this seems to be claiming that something in one celestial hemisphere isn't visible from the other, but guess what: this would be like claiming the sun should disappear for the entire northern hemisphere for the winter. This is just crazy.
