Despite how complex Finnish is, we can use linguistic evidence to prove that Finns are primitive as fuck.
Let’s start with the word for have:
…
There is no word for have.
Instead, Finns say “at me is [x]”. Unreal.

Next, the word for animal: “eläin”. This is derived from the verb “elää” which means “to live”. It did not occur to the Finns that plants, fungi, and other kingdoms are living creatures, so much so that there are different verbs for an animal growing and a plant growing! “Koira kasvaa, ja puu itää”. In fact, Finns didn’t recognise that plants were a concept; they hadn’t noticed trees, flowers, bushes, grass, et cetera, should be categorised into a common group. The Finnish word for plant was only coined by a Swedish-speaking biologist in the 1800’s.

Indeed, Swedicisms are common in Finnish, not just in vocabulary but in grammar. Even something as simple as future tense had to be calqued from Swedish. However, the reason why Finnish is such an intimidating language to learn is that most of the syntax consists of complicated grammatical workarounds coined by (often Swedish) translators. Were it not for these constructions, the Finnish language would be utterly incapable of expressing any intelligence, creativity, or ingenuity. Indeed, Finnish didn’t express these prior to the literature of Swedish native speakers.

Language is ultimately a logistical puzzle, and so it sculpts our brain. This is why Finns, with their primitive language, have never achieved anything throughout all of history. Every Finn of note was/is a Swedish speaker because an objectively superior language allows for superior cognition. Sweden should just annex Finland and force the Swedish language onto them.
