Yes, indeed! Jehovah God cares about humans. The Bible tells us that God gave man a perfect start ( Gen 1: 27, 31). Man was created to live forever in perfect conditions. But man rejected God's guidance and choose self-rule. Despite this, God made provision to remedy the situation which is a big sign of his love for humans. (John 3:16).
Aside from this, God has also set an appointed time when he will destroy those who ruin the earth and will cause lovers of righteousness to enjoy life in harmony with his original purpose. (Ps 37:10,11).
All the aforementioned are just a couple of reasons to show God really care about humans.
