We don't belong here.

[Angrboda]

The huge number of planets that we can't survive on is another indication that we weren't made for this place at all.

I agree. We weren't made at all. We just happened. If unnatural means the product of intentional design, then yes, some things we do aren't natural. And some apples are green. So what? The only way you get to any kind of conclusion is by making judgements about this state of affairs, and your judgements are purely arbitrary. We interact with our environment. So what? So does every living thing.
