Creatures capable of intergalactic space travel???

[deleted]

You're assuming that the meteors they arrived in were spacecraft, and not some kind of spore mechanism. (As the last poster said).

How they get off planet is another question.

It's not "sci-fi", it's SF!

The two people above me gave you the correct answer.

My input is to remind you that almost any level of intergalactic space travel by any alien creatures (or ourselves) is just as impossible in the real world as the travel of these creatures. The Laws of physics apply just as much to Klingons or future human civilizations as it does to primitive ape things.

Even more importantly its a movie, suspend your disbelief.

In addition to the replies above, I'd point out that the creatures are really just a metaphor anyway and not to be considered seriously.

In the film, Sam talks to the old lady about how kids today are 'monsters'. But Moses and his buddies are at heart essentially not cruel or evil people. Confronted with the kind of voracious evil they represent to people like Sam, they discover they aren't the criminal types they have aspired to be.

Well, let's shed some light on the subject, with an analogy.

Let's suppose there're life forms on Mars. Taking a walk around the park they come across the Curiosity vehicle.

It doesn't take them long to realize it's not from their world, and after a short analysis, they notice it's not very agile, doesn't seem to react to stimuli, doesn't seem to have a full spacecraft nearby, and thus, they begin wondering what that is and where it came from.

So, at this moment, they could choose between either of these options:
1) Show up at some forum questioning how's it possible for something to have intergalactic traveling capabilities, and be almost useless at the same time, or...

2) Wonder if actually something or someone else sent it there.

The latter would be an intelligent first, initial, approach to the subject. As to the former, well...

Loads of sci-fi stories have had primitive, animalistic (or plantlike) alien races doing this kind of thing, to name but a few; Starship Troopers, Day of the Triffids, the Alien films, various Doctor Who stories like Seeds of Doom.
