My current camera is a Sony A7Rii, Dawn. It is a lovely camera, but not cheap.
My first camera was a simple Canon point and shoot, for about $120, when I first started experimenting with photography. I found I enjoyed it, so I moved on to a larger point and shoots with higher resolution and more features.
I would start with something for about $180, just to see if you really enjoy photography, or if it might be a passing fad for you.
