Europa is a moon, and is very small compared to Earth. It's also very far from the sun, probably too far for life to take advantage of it's heat
The moon's oceans are under a thick layer of ice, possibly miles deep. With no light and little warmth except around any volcanic vents there might
be, it's unlikely that Europa could sustain life. Life requires light, heat and water on earth. Green plants could not produce energy without
light, and so there would be no food chain as we know it if Europa is indeed inhabited by primitive lifeforms.
