Question Proper grounding guidance for home

I have attached a picture of my main electrical panel.
I am looking for comments on grounding of a second hand house I just got.

If you take a look at the top of the picture, you see a big thick red cable. That is the NEUTRAL cable that comes from the electrical pole.
The two big thick black cables are the HOT cables from the pole.

At the left of the panel, there is the NEUTRAL bar. The NEUTRAL cable is connected to this bar. All neutral cables from ac outlets and other electrical outlets from my house are connected here.

But, also the GROUND (Green) cables from various outlets in my house are also connected to this bar. This bar ALSO has a bare copper cable that goes all the way to a grounding bar in the floor.

Questions:
Is this ok?
should I add (somehow) a ground bar and rewire my house?
Why was this done on the first place?

thanks for your comments.

Since non-US the rules are different. The grounding looks OK for a main panel.

I would be concerned that the breakers are over-sized and there is not a main disconnect/shut-off.

Looks around, I have a feeling there is a main panel someplace. Perhaps near the meter?
