Alien neednot be intelligent. Even a microbe not originated from Earth also can be classified as aliens.

Anyway... if there are intelligent aliens out there that are capable of reaching earth, it would be logical to assume some of them have human instincts (purpose is to exploit/enslave if possible. just look at wars amongs ourselves... and also against other organisms/their habitat). In reverse, if humans are able to reach other planets and found out its useful, we too, wont simply shake hands with aliens there. There has to be a scheme to exploit their planet.

It only take a "high ranking" alien's rogue gang/army to initiate a war with us, even though 99% of them might "come in peace".

So size matters. for us to be treated like a colony of ants, those aliens must be each be as tall as KLCC, for them to readily accept us as being tiny harmless creatures to them.

Even in the most kind/noble of human exploration team looking for uncharted land, there has to be one or few rogue ones who eventually anger the natives or worse, brainwash others to follow suit and wage wars on them. This is exactly what we as humans should fear, if the aliens finally landed on earth and propose a friendship. It only take one determined power hungry being (from our side or them) to start a misunderstanding... and there goes the neighbourhood!

Humans barely only scratched the tip of the icecube found on the tip of the huge iceberg in space exploration. Our history in space "travel" merely at its infancy.

Anyway... by assuming only via faster than speed of light travel can make them reach here easily (or finally)... kinda closed minded and one track thought, dont you think so ? Maybe they have other methods/technology that doesnt require physical travel from their planet to ours.

Well those scientist know better as they career revolves around these day in day out. There are certain law that are consistent across the universe. Based on that, alot of scientists managed to discover alot on space and what's surrounding our solar system within the last few centuries or so. Of course some old discoveries might erred (Eg Pluto is not a planet but a moon), but they're gaining more and more ground. THis applies the same as well in searching of extraterrestial lives.

of course by keeping an open mind and assume those law will be different in a different galaxy, its pretty hard to get started for serious researchers to pinpoint a place to start looking. For eg, no water = no life. So planets with no water will be assumed as no inhabitants. An ultra openminded researcher (or normal people like us) might start looking at EVERYTHING in hope of finding something, which is a pretty tedious tasks. Without a basic foothold we might leads to nowhere.

For eg. I want to look for a tiger. Common understanding tells me tiger lives in jungle. But since I'm frustrated of not finding any of them in my jungle, I open my mind and think, maybe there ARE tigers in the desert too (a different one that has special abilities to survive in desert, perhaps?). So I blindly go look for one in the desert. Pretty foolish eh.
