If, as is mentioned in a couple of Sci-Fi books/movies, they rock up offering to serve humans they're probably going to eat us!

I can't speak for all of humanity but I can say that were aliens to visit the earth that my first response would be to yell "oh shit", my second response would be to do that in my pants.

I'm reasonably confident that we'll find microbes elsewhere in our solar system within the next thirty-or-so years. The million dollar question is: will they share our DNA ancestry? If so, it's no biggie — apart from the cool implication that life started somewhere else and may even be from a different start system... If not then wow! Life gets started easily and the rest of the galaxy could be teeming with it.

Either way — I'd be seriously excited. Plus we'd have a nice new thing for the hoaxer conspiracists to get uptight about... That's always good for a giggle.

Depends on the circumstance.

I do however agree with the late Steven Hawking

I personally whole heartedly believe they exist. My holier than thou father thinks they are the fallen angels and that aliens don't exist. This is mind boggling to me. Through the theories I've seen. It just makes sense to me that they do.

If they don't exist then they just don't exist.

If they do exist, but don't know we exist, then oh well.

If they do exist, know we exist, but don't have the technology to reach us, then oh well.

If they know we exist and can reach our planet with far superior technology than us and are friendly and want to help us, then why haven't they yet?

If they know we exist and can reach our planet with far superior technology than us and are hostile and want to harm us, then why haven't they yet?

If they do exist, know we exist, and can reach us with far superior technology, then we better hope they are friendly, because if they're not friendly then we're fucked.

It doesn't matter one way or the other unless they make themselves known to us, and if they did, we HAVE to treat them like they are hostile. I'm not saying we have to initiate first strike or be violent, but we have to be extremely cautious. If they can reach us and they have far superior technology then it would probably be easy to do whatever they want to us.

So they either exist or they don't exist, and either don't have the technology to reach us and/or don't know we exist.

Or maybe they exist, know we exist, and have the technology to reach us, but they just don't give a shit one way or the other. We probably have nothing to offer in any way. Maybe they have rules to not interfere with other civilizations. Maybe they aren't allowed to interact with us or else it wouldn't be a valid experiment. Or a hundred other reasons.

So to answer your question.......I would be extremely cautious lol. How it would affect me depends on if they are friendly or not. Humanity would probably be scared shitless.

IF Extraterrestrials visited i would inquire about their point of origin . IF it was superior to this shit hole i would ask for a one way ticket out of here

It would depend upon the level of intellect the ET organism possessed.

I would be worried that Trump might try and nuke them.

I'd say, "I knew it," and move on.

Humanities first reaction would be to shoot it, if not that cut it open to discover its secrets (D'oh!), if it's microbial a lot won't believe it and they'll be the usual conspiracy bullshit (Boy do I have faith in the human race) or maybe, just maybe, we might learn something

As for my reaction, I wouldn't do anything except be really excited and if they arrived by trans-galactic transport hope to fuck they're friendly

In the majority of likely scenarios, my response would be "Oh right; I was expecting that sooner or later", followed by no action other than my standard daily routine.

Immediately join the Space Force.

Humanities reaction depends on how the media spins et arrival

I have no idea what humanity's reaction would be but mine would be awe struck and amazed. There is no action I would take or that I even could take.
