It found its way into a gravitational collection of neutral gas, and cooled, eventually getting sucked in to another gravitational perturbation, as star-formation happened all over again.

Only four per cent of the mass of the Universe is in the atoms that make up you and me, the stars and planets. Now watch the universe fly by, going from macro to micro. This is the biggest discrepancy between a prediction and an observation in the history of science.

Yes, back then it was too hot to have any atoms at all. Well, one epoch a carbon atom went on a bender with a helium atom and came out oxygen, but it doesn't remember much of what happened after that. Here you are, a human being, a grand Universe of atoms that have organized themselves into simple monomers, assembled together into giant macromolecules, which in turn comprise the organelles that make up your cells.

James N. Our galaxy, the Milky Way, contains approximately 100 to 400 billion stars.

The universe is vast. We know of its existence only because its gravity tugs on the visible stars and galaxies.

It was only by luck that this atom we're following wound up in a dense molecular cloud, shielded from this radiation. Although 10 80 atoms is a good ballpark value for the number of atoms in the universe, other estimates exist, mainly based on different calculations of the size of the universe.

Thanks again, and please consider this. But that's just for perspective.
