Although I find many topics fascinating (especially anything to do with time/space), I'm not really into a lot of this stuff either, and I talked about that right at the beginning of this thread. I used to be into it in a major way years ago, but there's only so much time, so I narrowed my focus on what's important for me. But this is such a major event that I wanted to say something to get it out there for people to prepare for.
Throughout history, we've had all kinds of visitors/friends, not just coming and going, but with actual outposts.
Elucidate - It's all benevolent. The stories of the abductions and mutilations are exaggerated. We actually owe a lot to our alien relatives, including the fact that they helped genetically mutate our bodies to create the different races (at our request), which created the different bloodlines - O, A, B, AB.
Fellforit - Like most things, there's going to be a mixture of reactions. Many of us here are probably thinking something like "Yes! It's about Freaking time!". If you have a fundamental religious background, this might look like the devil in disguise and just another way you're getting tempted. And every other reaction/response in between. The governments/militaries are aware of the possible scenarios, which is why it has taken so long to prepare the population for this. It will be interesting to see how corporations might make a grab for more power, or pretend to be on the bandwagon for energy conservation, etc. Expect some prices like oil to go up shortly so they can get as much as they can.
Movies were created to stir up emotions and get the worst case scenarios played out back in the 50's, then Star Trek in the 60's helped with curiosity about space, and by the 70's/80's movies like Close Encounters and ET were creating more heartfelt connections. It's all been to help prepare for the coming out.
