Is this a claim that Allah created us all other creatures as humans and then one specific one called Germans? I am mostly Finnish origin but also mix with some German and Asian genes but I am definitely the human. That´s why I claim that humans exist. At least I exist. I am sure about it.
You see, as I am partly german, it proves that humans and Germans are the same species. They can produce offspring. For two species from very different origin it wouldn´t be possible - like tigers and giraffes.
Ok, so you are a hybrid, which explains why you have an aversion to and like to ridicule race purity. It tends to be a common trait. Well, that is your choice to continue thinking that miscegenation "is great". I however utterly FORBID any of my offspring doing it, otherwise there will be extremely serious consequences if they ever even THINK about it.
You are also wrong about different species not being able to reproduce fertile offspring. Some CAN, and there are plenty of examples of it being able to occur out there in the animal and plant kingdoms. Just because I might be capable of breeding with a different species/race doesn't mean that I SHOULD.
