Just imagine, you could have been born as one of quadrillion of these guys, but instead you are a human, that’s more than lottery luck we all got, if you can read this.
The "you" (or: self) is a concept, a perception.
I am just me, and couldn't have been something else, or born in another timeline, or to different parents.

> The Veil is meant to ensure that people’s concern for their personal benefit could translate into a set of arrangements that were fair for everyone, assuming that they had to stick to those choices once the Veil of Ignorance ‘lifts’, and they are given full information again.
> One set of facts hidden from you behind the Veil are what we might call ‘demographic’ facts. You do not know your gender, race, wealth, or facts about your personal strengths and weaknesses, such as their intelligence or physical prowess. Rawls thought these facts are morally arbitrary: individuals do not earn or deserve these features, but simply have them by luck. As such, they do not deserve any benefits or harms that come from them. By removing knowledge of the natural inequalities that give people unfair advantages, it becomes irrational to choose principles that discriminate against any particular group.
I suppose it's implied it was "half of life" on a per-species basis. It's basically magic, so probably best not to think about it too much.
Not sure about the rest of Thanos's logic, of course...
Therefore, also it's not the case that "you can reincarnate into any of those life forms" but rather that all those lifeforms, including you, are incarnations of the same over soul.
So, you always already are both those forms and not, and have just forgotten it was so.
And, then, finally, when you do bad things to those other incarnations you are doing them to yourself: it's not that you have to reincarnate to have someone else do shitty things to you, but rather the case that karma is always already in balance.
Anyhow, just my shitty heterodox take based on a single poorly applied mathematical rule.
Be well, other self.
Also we think being human is the best because we are humans. Right between the start and the end of time in the centre of the universe.
Why some group is not empty is different from why it is me who is in that group, when I could very well be in the other one, like almost everyone. When the other group is much larger, then most potential "me"s will observe that they are in the larger, more typical group. The others will be surprised because they get the less common result, but most will not.
There are more intuitive examples than being human versus insect. Let's say, vast majority of people are not members of a royal family, so, knowing nothing else about myself, I should expect not to be, either. (Fits, afaik.) There are also some counterexamples, like that most people live elsewhere than in my town, but these are often tailored to me.
Going back to the plankton problem, I observe the equivalent of being a prince. Someone has to be, for sure, but is there a reason why me?
