Corrected entry: It becomes quite obvious as the movie progresses that the aliens want to capture and use (or digest) humans, so it defies logic that the first one to appear immediately starts vaporizing every human in sight. Since the people posed no threat, the only reason to vaporize them would be if the aliens simply wanted to be rid of them - which they obviously didn't. So this initial vaporization was simply a manufactured plot device by the movie makers.

War of the Worlds (2005)
Correction: Doesn't defy logic in the slightest. It seemed pretty obvious to me that the initial "invasion" (vaporizing every human in sight and starting battles) was to disrupt and take control of the human population. Thus making it easier to harvest human blood/tissue from the remaining population. (Which, from my memory at least, were implied to basically be used to fertilize their terraforming efforts/the red weed.) If you wanna take somewhere over, you can't just wander in and say "Ok, this is MINE now!" That's not how war works. You have to show force, assert dominance and then get rid of any possible opposition.
Correction: "So this initial vaporization was simply a manufactured plot device by the movie makers." This 'manufactured plot device' was written by Herbert George Wells, 110 years before the 2005 movie. While there are differences between the original novel and the 2005 movie, there are a number of similarities. One identical plot detail being that the aliens' tripods started by incinerating countless humans before harvesting them to fertilize the red weed. I can't recall if the novel explained why.

Correction: There are plenty of humans to go around. They don't need all of them. What they first wanted to do is collapse human society. That usually works if you start killing indiscriminately.

Maybe they needed 20 billion people. So we don't know that there "are plenty to go around." And again, the people they vaporized were no threat. And they didn't need to "collapse human society" (and you have no way of knowing what they "wanted" to do); they merely needed to remove threats. So, again, it defies logic to unnecessarily vaporize what's later shown to be desirable to them, if not required by them.

You don't know what the wanted to do either. Seeing them kill so many people, logically shows that they don't need all those people.

Maybe they didn't need 20 billion people. Maybe they didn't have the "human harvesting" equipment ready. Maybe they just felt like it. Who knows. Either way, I'm not sure we can't apply our concepts of logic to an alien race.
You might try reading the original novel. While I don't disagree that it defies logic, the fact is that the only person that could address the why of this was H.G. Wells. While the filmmakers changed a number of details to base the story in the present (2005), in the U.S., from a family's point of view, the tripods being buried...the basic story itself, on the aliens illogically torching lots of humans before they began harvesting them, is pretty much the same as in the novel.
