Lets say hypothetically we haven't already met and/or established contact with extraterrestrials, Kerbals or not. Do you think the government would tell everyone? I doubt it. It would ruin every major religion in the world, except I guess Catholics, since they already wised up and accepted the fact that they're out there. (which took balls, by the way) Plus, there would be rioting everywhere. I hope it wouldn't end up like that, but the general population is, I guess in laymen's terms, too stupid to cope with the news we were in contact with an alien species. It would be pretty hush hush IMO, unless there was irrefutable evidence that they were here (I.E an entire fleet just lands in a city) but if it were just a lander (like most good kerbals do when scouting a new location) I'm sure someone from the local government would go and retrieve it, and never speak a word of it. I doubt the Kerbals would try to fight us, but if they could cross a wild amount of lightyears to get here, I dont think we'd want to be picking the wrong bone with them, either. Those are just my two cents, however. Think of what you will, i'm just thinking logically and realistically. (Which in this case, isn't what I want at all, but we can't always get what we want.) I was just going to make that reference
