You'd expect heavier elements to be in the initial formation process.

Well, that could be true. There could be fragments of the "singularity" that attract the free hydrogen. In fact it is highly likely and most scinetists agree the central core of some if not all stars could be dense matter, which is what causes the hydorgen to accumulate and form a sphere.
But the process of small partical evolution states the simplest things form first and more complex things take more time. Hence the Universe was permiated first with free particles (electrons, neutrons, protons, positrons, gamma particles) and then as things cooled attraction formed atoms and the first atoms to form would be hydrogen. The simplest of all to make.
To make a complex isotope like U235 is almost IMPOSSIBLE for nature to do in any quanity. It is made by man through the Creation process by refining (centrifuges).

The big bang did not create very much in the way of heavy elements: the result was mostly hydrogen, some helium, and a bit of lithium. Everything heavier than that was created by stars; elements through iron can be created by any star, but anything heavier than iron comes from a supernova.

The space it's full with hydrogen, there are almost no other elements.
When the gravity pull the hydrogen atoms of and hydrogen cloud to become closer to each other, the gas starts to warm up and there are many collisions between these atoms.
As the cloud size starts to become smaller the temperature in it starts to increase. When the temperature it's big enough the collisions between hydrogen atoms become in hydrogen-hydrogen fusion, and the star it's born!!

There weren't enough around, and there still aren't, really. Hydrogen is the most abundant element in the universe, and is really still the only one around in sufficient quantities to form something as big as a star.

Hydrogen is the most abundant atom in the universe, Everything else is created from Hydrogen

Hydrogen is also extremely flammable. If a star were made of nickle it surely wouldn't burn.
