What do you guys think of UFO's?

[Ghieri]

Isn't that the official classification of an "Unidentified Flying
Object"? Its was unidentifiable and it was flying in some fashion. I did
not say it was of alien origin, so anyone who is quick to say,
"ALIENZOR TAKING OVER TEH WRLDSS!!", that's their own damn fault.

It is, but it happens with an annoying level of frequency.

It is, but some species show up out of random. And very sudden. And with
them being relatable to other and past species, perhaps these
"scientist aliens" are not able to produce a new species on our planet's
living conditions? perhaps they can't expand any further. These
"scientist aliens" may be smart, but they may not know everything. Again... Much like us.

For the first part of your post, I will have say Mutations. For the second part I challenge you to bring evidence of these scientific aliens. Otherwise this discussion stops being practical.

If they were real, perhaps this point is being proven otherwise? You do
not know their technology. Who knows if they have already discovered a
cloaking mechanism. They had most likely been around much longer than us
if they can fly through space, I'm pretty sure cloaking would be as
easy as 2+2=4. But I do not know what they do either. But they're
certainly smarter (and probably less arrogant and stubborn) than us.

This is the problem with your theory. It makes a lot of unfounded assumptions that can much more easily be attributed to simpler explanations.(E.g., there are no aliens)

I'm not saying I
am right and everyone else is wrong. But wouldn't it suck to be abducted
and no one believe you, and no way of proving yourself? I'll give SOME
people the benefit of the doubt, but most certainly not all.

They should expect disappointment when making those claims. I can accept that some people are being honest that they saw so and so, but I also say in the back of my mind: "They clearly misjudged the situation" Which is a better assumption to make than "They might actually be right! I should question everything I know because of this random person's claims!"

Occam's razor, FTW.
