This is the voice of the Mysterons.
No,
This is the writings of the Mysterons
We are here among you know,
No, that is, now.
Anyway, just watch it, that's all we are saying,
No, writing.
Yes, we are the Mysterons

> have been a site for life's origin . They could also have
> provided a refuge for thermophilic (heat-loving)
