I only have inside information on two of these, but they are so incorrect technically that he's lost all credibility. I'll caveat by saying I haven't listened to the podcast yet, but I will...

Elon Musk and other astrophysicist say that current missions to the moon would require 8 starship launches to fuel up a single moon trip.

What does this have to do with anything? I mean really, I've told some of you Musk humpers that Starship is not optimized for a moon mission, it's optimized for Low Earth orbit Starlink launches. Second, 8 launches???!!!!

The official number is 16, and there are several credible analyses that show it can creep over 20. I'll be honest, one thing I didn't anticipate with Musk's epic Starship failures is that it would retroactively create more moon landing deniers.

The van allen belt with the extensive radiation that would make it impossible with 1960’s technology for anyone to survive through it, much less live into their 80’s.

This is actually a decent question, but with very modest googling he'd have been able to debunk himself. First, one of the main things that makes modern electronics susceptible to radiation are their small size and density. We didn't have that problem in the Apollo days as integrated circuits were still years away from widespread use, although the main guidance computer on Apollo did use early ICs that were not very dense, therefore not as susceptible to radiation as modern chips. The other thing is that radiation events happen in cycles (they last about 11 years), and the Van Allen belts are not a constant amount of radiation from earth to the moon. We've looked at Apollo's trajectories compared to solar cycles, and compared to worst case Van Allen belt radiation, and discovered that while the Apollo folks knew that this radiation existed, they got pretty lucky in when they launched (solar cycle minimums for the most part) and their critical ops (engine burns, dockings, EVAs) tended to dodge the worst case areas of the Van Allen belts. We think this was mostly by chance as some of these environmental aspects wouldn't be discovered for another 20 years. And as for human exposure, the shielding of the spacecraft was enough to give decent protection given that they launched in a solar minimum. Today, for example, we can measure radiation events with GOES satellites, and will scrub launches if there is a solar flare etc. that causes excessive radiation. And as I said before our electronics are way more sensitive to radiation today than they were in the 50's and 60's.
