Extremophiles exhibit surprising capabilities to thrive in environments that would be lethal to most other life forms.

“every time we think we got those bugs figured out they do something crazy and we're like wait what do you mean you can live on a nuclear reactor wait what do you mean you can live two kilometers down in a subsurface in the subsurface and we find you when we're mining for gold”

Life on Earth is highly resilient and would be difficult to eliminate entirely, as it exists deep within the crust.

“if you think about life on the earth you would actually have to melt our planet to about 10 km down to actually eliminate life because there's life down to about 10 km that deep”
