*throws two cents in*
If aliens do exist , I think most of us wouldn't / can't say for sure what an alien would look like. For all we know , the so-called "crazies" ( ie alien conspiracy theorists , those who have claimed to have been abducted , those kooky "ancient astronauts" guys , ect. ) They could be right. Maybe not a hundred percent right of course but there could be SOME truth to their claims and beliefs.
Until and unless it happens to you...you aren't an expert on aliens. Don't pretend you are. You should stop calling others crazy , even if they are. So what if they're crazy? As long as they aren't hurting other people or themselves....Let them be "crazy". They're not hurting anybody. They're just telling stories and maybe being stupid and weird , yeah....but they're not hurting anyone. Weird stories , but stories nonetheless. Why let yourself get so worked up about it anyway? What did they ever do to you? What's so upsetting about it? You're afraid they may be telling the truth and you just can't deal with "omg aliens"?!

Is that it? Or are you just annoyed about and get tired of it? 'cause I can kind of understand that.
Until and unless it happens to you , you can't and don't know for sure on the whole "do aliens and ghosts exist?" For all we know , unicorns can exist and have learned our language and are just not appearing to most of us because they know what huge butts we are. I say humans aren't all that great on the whole even though good people do exist among us. So I don't blame other creatures at all for avoiding us like the plague whenever and wherever they can. Hahaha. We do have this knee-jerk reaction to kill anything that scares us and things we don't understand. We're the real monsters. ( Ever played Always Sometimes Monsters yet? Yeah, the title is kind of stupid but I get it's meaning and what they were driving towards with the game. )
But from what I read , if any of it's true...it would not be a cool fun experience. It would be terrifying and some aliens do reportedly look like the stereotypical "greys" / "grays" and "reptilians" we see in the movies sometimes. I've read some interesting alleged "true stories" of other creatures as well that may or may not have come from space. Like this one person claims they saw something that looked like a mix of lion , human , and scorpion. And they were HUGE or pretty big. I would love to see something like that from a distance and if they were non-hostiles I would love to make friends with one of THOSE creatures if they really exist. Hahaha!
But people can lie. Some people lie. People can and will betray you.
I'm not saying all alleged taken - ( abductees ) - are liars but...I am not going to trust them all either.
They are strangers and while the stories can be interesting to read , take 'em with a grain of salt.
Sympathize if they swear up and down they are telling the truth but having _some_ skepticism is healthy.
It can be hard to judge what the truth is at times , especially online.
But darn, they sure can make for good scary / interesting stories , eh?!
Nothing short of going through an ordeal themselves is ever good enough for hardcore skeptics. ( in my opinion they are stupid narrow-minded snobs )
And nothing will ever sway a believer from their belief.
Those who believe don't need "proof" , they already have it via their own alleged experiences and faith or whatever.
*shrug*
But why wouldn't aliens grow , learn , and evolve just like other creatures?!
Why wouldn't they be able to look like us or be in disguise with some sort of technology or stuff like in that show Face Off with good cosmetics and prosthetics and what not or whatever...you know what I'm saying...?? *blushes and laughs because she can't spell some words right apparently* I hope you get what I mean. Like magic movie tricks...you can so much now in the business , it's awesome and fun to watch the transformations but people who are masters of their art ...that skill could be used among outsiders ...others as well if they learn / know it. Aliens could learn to disguise themselves in various ways but then again why would so many of them simply not bother or seem stupid enough to not take better care if they are going to take people and mutilate cattle and whatever else it is aliens do.... *shrug* Know what I mean, Vern?
Why would they remain basically unchanged from what they may have been or were originally.... ? *shrugs again*
I don't know. I'm not an expert or anything. I'm more interested in bat people - ( well anyone or anything with wings really ) - unicorns , grim reaper and other psychopomps, fairies , merfolk, leviathan, behemoth, other giants, elves, vampires, and other so-called imaginary...legendary...and mythical creatures that fascinate me... than in aliens or bigfoot. I don't get obsessions with aliens or bigfoot. Even though I am not sure what to think about aliens other than "ok , aliens are obviously evil from everything I've read about them if they really do exist. Even the ones that are supposedly nice are probably faking it...if they're anything like humans than in a way they're worse than humans because they're so different and you'd think aliens would be smarter than us and everything...since they are allegedly older species and blah blah blah..."
Those are my thoughts. LOL
So , if I saw an alien I'd probably be angry...maybe scared for a while or longer...I don't know , but certainly angry. I would try hard to control the urge to be a judgemental killer , if they exist I'm already biased against most if not all of them.
I would be really angry if they tried to manipulate my emotions or succeeded at manipulating me...because I read some , if not all , aliens can do that. Ugh.Heh.
But thankfully it hasn't happened and I doubt it ever will. I really wish that if they do exist they continue to leave me and my family alone. They should leave other people alone too. And if the MIB exist they are not like the kinda cool guys in the movies. From what I've read so far, the "real" MIB are jerks.

Anybody else here play Spore?...or Creatures? I don't have Creatures yet but I finally have Spore and played that for a while. The creatures we make in Spore. What if there were really creatures like the ones in the spore-pedia? Would you think it would be awesome or scary or both , fellow Spore fans?
Wooow...my post ended up being sooo long. Sorry about that, folks.
