The layer suitable for life is the biosphere. This is the zone on Earth that supports life, extending from the surface to several kilometers into the atmosphere. This layer provides the necessary conditions for life, including the right temperature range, water, and atmospheric gases.
The biosphere isn't the only place where the potential for life exists. For instance, NASA's research on Europa, Jupiter's moon, suggests a salty water layer under its icy surface could potentially harbor life. Europa: A World of Ice, With Potential for Life – NASA's Europa Clipper This highlights that the concept of a "suitable layer" for life is not limited to Earth's biosphere and can potentially exist in other celestial bodies under different conditions.

The "good" ozone layer, extending from 6 to 30 miles above Earth, acts as a protective layer shielding life from harmful UV radiation. Ozone However, this is a specific part of the Earth's atmosphere within the broader biosphere.
