Before anyone wastes too much time reading the posts, I'll see if I can sum everything up:
WTF are we spending all this money on space when there are hungry people on Earth!
A lot of products and knowledge come out of these projects. Besides, we spend more on a war than this stuff!
Can't you see that this is in Europe? Quit thinking the USA is the only country out there!
Aliens are too smart to come visit us. Earth people are dumb!
This will never work! Don't you get that any alien civilization would have evolved in ways we can't fathom?
Yeah, but some evolutionary and physical principals are universal!
No they aren't!
They will find aliens any minute now. Just run the numbers!
Those numbers are flawed and will never work!
This isn't even original! Just look at these links to a book that I once read that had similar ideals!
*random yelling and fighting way off topic*
I hope I hit most of the major talking points and saved some of you some time.
