Earlier quoted context omitted.
Everything is nature , but clearly human society is also distinct. Both can be true. Some anthropologist philosophers have referred to this as "first nature" and "second nature", second nature being human society which is also part of first nature but distinct from it.
But you're making out that indigenous people are part of this "first nature" rather than the "second nature", while industrial civilisation is strictly "second nature" which is frankly racist.
Other animals such as orcas also have been shown to have societies, language, culture, and history that is passed onto children. You could perhaps say that is also second nature.
Call it what you want, but clearly modern human society is distinct in that it stands above (quite literally in the form of cities) and uniquely has the ability to threaten the rest of life on the planet. While at the same time being part of nature.
Humans are part of the surrounding ecology whether we recognize it or not, as others have noted in this thread. The difference is many indigenous societies have tended to recognize it and integrate it into socio-cultural practices as a necessary part of survival in their local ecology, while our modern human society mostly does not.
Consider the Kucadikadi people of now-Mono Lake , whose autonym literally means "eaters of the brine fly pupae". That is how closely their society, culture, and language is related to their local ecology, which "evolved" (in the 2nd nature sense) out of thousands of years of human society development and survival in that place. Notably their society has not developed to threaten or extinquish the brine flies on which they depend.
