TBH statements like these really grate on me. Yes, Earth will be fine in the same sense that you'd be fine if you surgically removed your arms, legs, eyeballs, ears, and tongue and then were fed intravenously and your waste disposed of for you. You might live a long life and have lots of nice dreams.
The reality is that we are in early stages of kicking off a cascade of effects that could wipe out the majority of the food web on Earth--let's say, everything larger than your finger. Yeah sure, insects and microbes will reboot it all--in a hundred millions years, if ever. Wonderful!
To make such flippant remarks about so profoundly annihilating the bioversity of this very special planet is not helpful in the dialogue.
Let's please work on this problem seriously.
