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
