When the meteors are seen approaching and then passing over, there is a whooshing sound. However, meteors travel many times the speed of sound. They might have been able to watch them coming, but they wouldn't have heard anything until they heard the boom from the sound barrier being broken.
Despite several days of meteor bombardment, when O'Neill leaves the caves the sky is clear. No smoke from the fires; no dust from the multiple impacts.
After spending 3-4 months on a "primitive" planet, Jack's hair remained neatly trimmed. However, they do have cutting tools and the native inhabitants also have neatly trimmed hair. Scissors have existed on Earth for at least 5000 years, so it doesn't require particularly advanced technology to cut hair.
The "meteor crater" that O'Neill is standing in is clearly a mining quarry, not an impact crater.
It clearly has been excavated by machinery.
Carter shows a detailed sky map of the planet's solar system, including its asteroid belt.
This would only be possible with a number of large telescopes and years of astronomic viewings. Or if there were satellites in orbit from which they could obtain photos and radio images.
As the episode relates, the SG team had only been on the planet for a week at most. There couldn't have been such a map, especially one which also showed an asteroid debris field.

When shoveling the sand after the Stargate was buried, O'Neill holds the shovel like he has never seen one in his life.
