I saw in a documentary that 5 or 6 objects with a 500 km diameter hit the earth when it was just formed. Also, an object with the size of Mars hit and caused the formation of the moon and tilted the earth. Considering the perfect orbit of the earth, nearly circle, I think these didn't affect either. Am I correct? These were very big events. Please comment.
