Deception is..
That Humans are Young Race.

Some sort of slave race.. made to work on mines..

No..They were made Slaves...Was it natural or was it war.Not sure yet.
But I think it was War. Really big War.
But what destroyed Mars and Earth Human advanced civilisation was not joke.

Because it seems to me..Old Ancient Humans managed to destroy Home World of attackers too..so as an result.
All of them got stuck on destroyed Earth..with only limited means and knowledge available to all of them.

Yeah.. Life is full of Irony Lucy.
