As pointed out in one answer, not all living things
need oxygen. In fact anaerobic organisms, which
can do without oxygen, may actually be killed by it.
The other answers about eggs are correct, the
egg shall is permeable to gases, but by diffusion
not osmosis. Osmosis refers to the diffusion of
a solvent, usually water in organisms, though a
semipermeable membrane separating two
solutions.

The egg shell is certainly porous.
However, not all living things need oxygen. Some bacteria, fungi and other simple organisms can live in anaerobic conditions as they can burn glucose in the abscence of oxygen to give lactic acid, which enters the Krebs cycle (fermentation)

There is an air sac at the bottom of the shell (that's the white stuff that floats in the clear fluid when you make an egg). It's basically oxygen and helps the little bird breathe.

Egg shells are porous and allow gas to pass through them.

Shells are porous. It's osmosis.

the shell of an egg is porous, oxgen can get in, you just can't see it!
