The first heat engines were fire pistons, which go back to prehistory, so 12k to 25k years sounds about right. The next application of steam to make things move happened about 450 BC, about 2.5k years ago. Although not a direct predecessor to the ICE, they all are heat engines.

Fire pistons are so damn cool. Yeah, that makes sense then.
