Hi, Alex! Your English is much, much better than my German....
Your final question is one of the reasons I spend too much time on these boards. These same people will eat shrimp, or mow the yard on Saturday and travel to a football game on Sunday, or borrow money at interest from another Christian, or readily admit that the Earth orbits the Sun. But ask them if humans are related to any other life on Earth, and they get angry and deny it. It's interesting - and very odd to me.
And I wonder if Jesus really just gave the poor boy some phenobarbital....
