There's the beginings of life apparently on Mars. Well, they are looking
for it, and apart from hopeful dreams of finding tiny green aliens that
speak english the most probable find would be some very fragile micro
organism, or nothing.

Now wind the clock forward a million years or so. We here on earth will
have probably persished, but those organisms on mars may well develop into
self sustainable alien lifeforms. Tiny, maybe green, who knows?

However, somewhere in that distant future, some of them are going to come
across a decaying but still highly radioactive source and after the visit
suffer the indignity of being born with two heads and three arms.

They will need the time machine to come back to now to find the highly
radioactive source as it will have decayed in a million years or so.


Is this right? Do the aliens have rights not to have their cell structures
modified in that way? What if they discover time travel and come back here
to give us a telling off?

Nobody will discover time travel, they would already have been here if they
did.
