[ExI] Earth's deep crust could support widespread life

We see this conquering of the (difficult) niches AFTER an evolution
pressure has been put on some softer creatures. Only after a lot of
hospital cleaning has been done, we have a lot of bacteria flourishing
there. After a lot of antibiotics used, we have some penicillin resistant
germs. After a lot of pesticides used, some poison resistant bugs arrived.
Perhaps you can put a scorpion on the Moon, see it crawling for at least
some time. Cockroaches along with some resilient plant can perhaps survive
Mars conditions for an indefinitely long time. But not without the Earth
which nourished them first.
First you have to have a nicer environment for life to begin and especially
to develop, I am quite sure.
