How NOT to colonize a planet

Rating: 5/10 (18 May 2017)

After watching Alien: Covenant I can't stop thinking that all these movies are based on one underlying condition: human stupidity. If it wasn't for the characters' doing their best to win the Darwin Awards, we wouldn't have any movies. Let me explain.
With the Universe being >14 billion years old, and the Earth ~ 4.5 billion years, any other planet which is as old as Earth with an atmosphere resembling that of the Earth, will inevitably have some sort of life form. And even if for some reason the evolution didn't create intelligent life (though I'm sure it would), there would be Life. Therefore, the whole idea of bringing in people to colonize this kind of planet is stupid in itself. Colonise my ass dumb-ass.
Then. Even if, for some reason, due to some really bad catastrophic events, some life form on this Planet had been annihilated, but the vegetation is booming and atmospherically everything gives you thumbs-up, then we already know who will probably inhabit this kind of planet. Guess who can survive most dramatic cataclysms? Micro-life, bacteria and viruses. Some of which, as we already know, can even survive in the outer space without any problems. Can you imagine, they don't even need spacesuits to survive? And we all know it because that's what Earth went through quite a few times.
Therefore, those "colonizers" who jump out of their spaceships without any proper reconnaissance are going to win the Darwin Awards by default. Why the *beep* don't you give the robots do their job, dumb-ass? Are you so unhappy that robots took away some of your jobs that you want to take away some of theirs too?
And what kind of instruction tells them to walk around this planet without wearing any sort of suits or protection! Oh, is the Earth-ish atmosphere good reason enough? Did they forget that it wasn't just the European colonizers who wiped out the Ingenious population of the American continent, but the microbes? And if walking around without protective suits is not killing you fast enough, just go poke your nose into everything you see, sniff those flowers, touch those unfamiliar objects with bare hands - because why the *beep* not...
