I hate to differ, but that's not even close to being true.
Life is found in practically every place we've looked on this planet, including in boiling sulfur springs, and even within solid ice. Even rocks in the most barren places on our planet, have been found to contain microbial life.
Scientists refer to these lifeforms as 'extremeophiles'. Some environments on moons of other planets are even less inhospitable to life, as some on Earth that currently have life within them.
Prove me wrong. I did say by objective measure. The only two I know of would be a mass ratio or a volume ratio. I figured that the mass ratio is less than one part per billion.

Sure, but most of the Earth is inanimate by a wide margin.
