Is it possible for life to exist on the core of a gas planet?

I was thinking of writing a story and had the idea of having a society exist on the core of a gas planet. The core would be similar to earth with a breathable atmosphere similar to ours above it but still have the outer atmosphere of hydrogen and helium above it as these two gases are lighter than the mainly oxygen and nitrogen of the inner atmosphere and so the breathable atmosphere would sink down and allow the lifeforms on the planet's core to live. I was just wondering if this is possible at all in regards to science and its limitations or if this could never happen in real life.
