An obviously advanced civilization sends an exploration ship to our world. Earth’s response: light show to let them know we welcome them and to show them where to land and meet us? Radio messages sent on all frequencies to let them know we eagerly await a peaceful meeting and exchange of ideas?
How about MISSILES OF FLAMING DEATH!!
The aliens somehow managed to avoid detection, perhaps because they are able to travel millions of light years they have technology somewhat past our own. They land and attempt to contact us. Earth’s response: Lay out the red carpet? Ceremony of Celebration attended by top officials in honor of our new visitors?
How about CAPTURE AND BRUTAL INTERROGATION!!
Alien visitors tragically crash land on our planet (see scenario 1 above). Earth’s response: reverent recovery of their bodies? Touching funeral to honor their attempt to contact us?
How about COLD AND UNCARING DISSECTION IN A SECRET LAB!!
If we detect them in the air, our first reaction is to try to shoot it down if it’s flying. If it’s on the ground, our first reaction is to capture, hold and brutally interrogate these explorers. If we find their bodies our first reaction is to dissect them. Seriously, what are you guys thinking? Are you really that crazy?
So, when these technologically advanced being send their follow up expeditions, because “Hey Blarkthar, what ever happened to that ship we sent out to that solar system on the edge of the galaxy that sent the ship with the platinum disk saying hello and asking us to come visit?”, What are we going to say?
