I Shot an Arrow into the Air - S1-E15
Corrected entry: When Corey takes his last drink of water before he finds the telephone poles over the hill, you can see plants growing out of the rocks right behind him. Since he is supposed to be on an "asteroid" no plant life should exist, but then again since an asteroid contains no atmosphere, meaning no oxygen, they shouldn't be alive in the first place.
Correction: This is not mistake even by far. Of course they can live and of course there are plants on this asteroid - it is not an asteroid, but a planet we all know very well called Earth. On Earth there are air and plants everywhere.
