Is Earth the next target of a nuclear attack by these Space Aliens?

Question

How much longer do humans have before they do to us what they did to Mars. Can Obama save us from the Aliens?

Dr. Brandenburg will present how Aliens wiped out the Martians and how we might be next. The presentation will be at the 2014 Annual Fall Meeting of the American Physical Society in Illinois this Saturday. Had I not made other plans for the weekend I would be tempted to drive out to Monmouth College to attend.

Answer 1

If they are powerful enough to invade and conquer us then we are lost. But if not and they want to come here they are going to have to find friends among us who will let them in. And of course who would be their friends? Our enemies would probably gladly let them in just to get rid of us. Just like the enemies of the Azteca joined forces with Cortez to take out the Aztecs. Just like the enemies of the western tribes joined forces with the English to fight the French who were allies with the tribes who were enemies of the tribes who befriended the English. In other words. If this earth is a mess and none of us are getting along we do not stand a chance of avoiding being invaded and conquered ourselves the same way we have been doing for thousands of years. In fact that already may be happening right now in front of our eyes and we don't see it.

Dr. Wernher Von Braun did say. “And remember Carol, the last card is the alien card. We are going to have to build space-based weapons and it is all a lie.”ag

Answer 3

The Daily Mail is not a reliable source of science news.

Answer 4

No... Earth's not next - they *want* Earth... they'll need to take us as is - with conventional weapons only, otherwise, they contaminate what they'd like to take.

What we need is someone to plant a computer virus in their mothership....
