Re: Where are the trees.

The death of Mars 4.2 billion years ago is a guess - an 'extreme extrapolation' in fact.

Given we can't even date the Sphinx it's a bit soon to be able to claim the date of something so far back in time most have no concept of it.

The fact Mars has enough magnetism left today to maintain pockets of air is an indication that it died a LOT sooner than 4.2 billion years ago.
