Of course they are. Mutations are random and so most of them are not significant (for example, most humans have about 60 or so) many others are harmful and just a few, very rarely, are beneficial. The beneficial ones - those that confer and advantage for survival and reproduction in the environment - survive and reproduce more and hence spread through populations, while the others do not. That's called natural selection.
I believe in science and logic, I don't believe randomness can achieve a good job by accidents that can
be beneficial for one species, can you give me an example of recent good mutations that was beneficial for
humans in our recent days? or have we wait millions of years to watch its effect?
The light sensitive cells in the retina point backwards (away from the light), the nerves (that point towards the light) then have to trail over the surface of the retina and go though a hole, leading to a blind spot. The eye can only focus properly and see colour in a tiny spot in the centre, so the eye has to continually scan the scene and the brain then has to do lots or 'post processing' in order to give the impression of a good, sharp visual field. If a human engineer had designed it, they would rightly be call incompetent...
The human's eyes is amazing and working perfectly, I can see a great designer behind it than the inanimate stones
doing it by randomness?
Blatant question begging. You have just assumed that the thing that makes logical choices cannot be the brain by itself, in order to argue that it cannot be the brain by itself...
I can't help if you can't recognize your own self and thinking that the brain's material is what you're.
