Yes, and famously the ancient Egyptians used steam power for religious trickery and to open a pair of doors to one of their temples.

The trick is that without much better metallurgy and pipework, it wasn't possible to create the kind of high pressure needed for a steam engine.

Same thing goes for evolution. The rough concept had been around for a while; it took until "deep time"(earth being billions of years old) was proven that we knew that life actually had the kind of time needed to evolve.

The first useful industrial widespread steam engines we low pressure water pumps weren't they?

High pressure only came later

To be fair, it was low pressure because it operated by creating a partial vacuum from condensing steam.

It took cannon technological development to make the high-pressure chambers for steam engines

If you mean the "Baghdad Batteries" unfortunately not. Deeper analysis has revealed that it was a sort of prayer system. They'd write or offer something, seal it in a small metal box, then put that in a larger jar.
