The evidence of the giant impact theory that suggests Earth and the moon may have once been in the same place is the similarity in the composition of moon rocks and some Earth rocks.
To arrive at this conclusion, scientists have studied samples of lunar rocks brought back by the Apollo missions and compared them to certain types of rocks found on Earth. They have found that the isotopic composition and trace elements in these rocks show strong similarities, indicating a common origin. This suggests that the moon and Earth likely shared a common material during their formation, which supports the idea of a giant impact event where a Mars-sized object collided with the early Earth, leading to the formation of the moon.
Therefore, the correct response would be: "The composition of moon rocks and some Earth rocks are similar."
