Without any single act of human intervention (before we were even a distinct species) 99.9% of all things that ever lived had gone extinct.

Humans may have slightly increased background processes but, practically speaking, we've contributed to less than 0.1% of all extinctions.

Life dies. Some life survives and then dies. Extinction is the rule and the norm for most species without humans ever having been involved.

Furthermore, humans are part of nature and the universe and not somehow apart or removed from it so, even our 0.1% contribution is also part of natural extinction.

Perhaps it's normal and commonplace for a species to cause some accelerated extinction once it reaches a certain level of technological advancement.
