Next time you make a fire, set a stone in it for an hour, or so.

When the flames die-down, place a leaf on the stone.

Imagine the stone being as large as The Moon, its gravity hugging all the
byproducts of that thermal transfer...

Huh?

Exactly.

What exectly?

It's not like the earth was a bb that gradually captured some gases from
across the Universe...

I think all elements were there in the beginning in the spiralling
cloud of dust and gas out of which the Earth and other planets
formes. The Earth had lots of gas in the biggining, but being so
close to the Sun, lost much of it over time due to the solar wind and
the Earth's relatively modest gravity. However, its magnetic field
did help it keep as much atmosphere as it has.
