How do we know that creation was subjected to vanity?

According to Romans 8:20-22, creation itself was subjected to vanity and frustration not willingly, but because of Adam's transgression. This act introduced corruption and decay into the world, impacting not just humanity but all of creation. The Apostle Paul teaches us that the whole creation groans and suffers in anticipation of being set free from this bondage and restored to its intended glory. This reality points to the profound effects of sin and God's ultimate plan to redeem and restore the universe.
