fly through software wanted

I have debian 11.0.0 (bullseye) with main software repository. Using that, I can make 3d models and view each model at diffrent angles. I prefer stl format and can download many models from internet.

I would like to arrange the models into a world and then fly through the world and record video and screenshots. I think the software category that does this is game engine? I like software that is easy to learn and uses script. What software do you recomend?

OK, so this is a blender forum. Is there blender script that does this?
