The colonel says he's at 4.3 light years, but Rod Serling says he's at several million miles. 4.3 light years is 2.528e+13 miles. The two distances are nowhere near each other.
The astronaut informs base that he has more power because he repaired "solar panels". He also makes it quite clear the local star has not risen yet, and it has been night the entire time. Solar panels don't work in the dark, so this would hardly increase his available power at the time he was speaking with base.
Cook talks to his home planet as if they were on the same planet (i.e., no delay between the comments). He has stated that he is 4.3 light years away. If he sent a message, it would take 4.3 years to get back to his planet and another 4.3 years to receive the response. No matter how advanced Cook's technology is, it can't send a radio signal faster than the speed of light.
When Adam exits his ship and sees the drawings in the dirt, he calls out "Come on down and meet your genial host". However, he is the visitor to the planet, not the host.
However, it is obvious, he is inviting the other person to come out of hiding and visit him at his ship. As such, he is going to be the host of their first meeting even though he is an alien on the planet.

The Probe 7 spaceship crashes on the planet at a downward angle. All internal items (and controls) of the space craft are also angled - in the same direction. While Adam Cook is communicating to his home planet, the video also should be angled down. However, the video transmission is level.
When Adam hears a rustle in the bushes, there is evidence of a newly trimmed branch on the tree to his left.
Cook misuses the word "galaxy". His explanation to Norda of his current situation - that he left his own "galaxy" and came to the nearest habitable planet - is highly suspect, as any two planets separated by 4.3 light years will be in the same galaxy. It is likely he means "solar system".
In the opening scene, when signing off the radio transmission, he addresses the general as Colonel.
