Look at the claim (above) for 2003 & then for 2018 & today.
I am more than willing to admit that We & Mars are rather close together today. I also have NO problems making claims about closeness as long as we don’t go BEYOND 400-years. That is it.
All bets are OFF for distances prior to that. We just don’t know. We don’t have any measurements. We are still trying to nail down orbital distances, shapes & periods.
60,000-years ago. WE HAVE NO CLUE.
