> Most of vertebrates (including human's ancestors) lost the 6th sense of electric fields in process of the evolution.
Human ancestors are not human. Also, the ancestor you are referring to was a fish, and could only sense electric fields under water. Why would the ability to sense electric fields under water be an evolutionary advantage for humans who don't live in water? If it's not an evolutionary advantage, then there is no reason it would propagate.
When I said 5 senses are better than 4, I was clearly referring to senses that are useful in our environment. Answer this question: is a deaf person, all else equal, more likely or less likely to survive and procreate relative to a hearing person?
> Moles went further to loose sight as well.
Moles have eyes and can see. Their vision is just not as detailed as humans. Highly detailed sight isn't an advantage for creatures that live in the dark. However, hearing is a huge advantage for people who live in an environment where sound waves exist.
You're clearly wrong here. Stop reaching so hard and just move on.
