From what I've learnt about evolution has led me to conclude that evolution is nothing but an insult to my family's intelligence. The idea that my family has the intelligence of apes, and that my great grand dad was the brother of a gorilla, does no fit well with us. That’s a car that just won’t drive in our family.
Then my post was correct.
You really should read up on evolution, it'll do you good, if only so that you can understand what it is you are arguing against.
Evolution does not claim that your family has the intelligence of (other) apes. Of course, like all humans, they are a species of ape but they have evolved to become much more intelligent than other species of ape, or any animal for that matter.
You great grandad was not the brother of a gorilla. No one in your family is related to gorillas. You didn't even evolve from gorillas. The truth is that if you trace your family history and the family history of a gorilla back for millions of years, eventually you will find that you have a
common ancestor. That is, an ancestor that both you and a gorilla is decended from. This happened so long ago that you'd never be able to be sure at what point you'll reach this common ancestor, but you can be assured that no one in your family is or was the brother of a gorilla. Rather, you are both ridiculously distant cousins, although you are more closely related to every other human than you are a gorilla.
Try reading about evolution, it's an interesting subject whether you believe in it or not. I'm going to make an assumption that your family has taught you what you know about evolution, and if so they are as wrong as you are. If you would like I can give you some links to read up about it on.
