Don't want to be a smart-ass, but since you are being one, I can't resist, too: Porsches come from Germany, not Austria. The founder (Ferdinand Porsche) was from Austria, but the company always was a german company. So there.
Why should we not be able to detect a civilization that is, say 50,000 ly away and existed 50,000 years ago?
We could actually theoretically detect signs from civilizations across the whole visible universe, problem is, they would have to have emitted signals in a very narrow time frame (400 years if they would send signals easily detectable with post-Galilean equipment, a lot less for harder-to-detect signals).
>... no one ever teaches people how to hold/use a mouse...
This reminds me of a guy I met in college who actually uses the mouse upside down, i.e. with the cable pointing towards him. I have no idea why (neither does he). I mean, imagine this: it's the first time you sit down in front of a computer with a mouse. You reach for the mouse, move it to the left, and the pointer on the screen moves to the right. You move it down, pointer moves up. Also, the mouse buttons are so inconveniantly placed that you can only hold the mouse with the tips of your thumb and your ring finger, if you want to be able to move it and press buttons at the same time. How the hell do you NOT realize that you need to turn the thing around? What a guy...

When did you look at an Audi the last time? I'd say they make pretty great cars nowadays... Then again, I'm driving one, so I might be biased :)
