Would You agree that the Earth is uniquely designed for us not merely to eke out an existence but to enjoy life?

I suppose so, if you enjoy hurricanes, skin cancer, and poison ivy.

no. would you expect to exist on a planet that was totally hostile to your existence? You wouldn't exist to complain about it. Your very existence demonstrates that the earth is very good for your existence. Otherwise, you wouldn't be here. You would be someplace else showing wonder that such another place was perfection, and claiming it had to be designed for you.

A lot of people are not really enjoying their life.

Why did God make a planet mostly covered in water if we're land mammals, and why did He make most of that water salty so we can't drink it?

So what do you attribute hurricanes, floods, earthquakes, and volcanos to? The "Creator" having a bad day and taking it out on us? Most of the things on this planet will kill you if you don't know how to treat or deal with them. Jump in a deep pond - if you don't know how to swim, you die rather than enjoy a cool refreshing dip granted by some magical man in the sky. Why not pet a lion? No. We are a product of our environment. Our great ancestors adopted traits that let them survive and thrive in this world. It's called - ready for it? - evolution. BTW, if everything was made so well to fit us, why do some fruits reside in trees so tall we cannot reach them without having to risk life and limb by climbing the trees? Why are there predators - big cats, wolves, bears, etc. - that would kill and eat us if we didn't avoid them? Why don't fish just hop out of the water and into our boats and nets so we can eat more easily? Be critical in your thinking.

The Earth probably would have had all those things with or without us... Earth wasn't made for us; rather, *we* are a result of life on Earth...

Yeah, every time I feel those bitter Arctic winds, smell the putrid odour of rotting vegetables or hear the feral snarl of an animal about to attack the only thing I can think about is how thoughtful your creator was.

Do these gifts not reveal our Creator’s thoughtfulness, tenderness, and generosity?

No.

That's in answer to the last question in your update.

Despite the fallen nature of man and the doomed world, God did create the earth for our pleasure and for mankind's domination, as part of God's plans.

Would I agree that the Earth is uniquely designed for us not merely to eke out an existence but to enjoy life--

No. That's childish nonsense.
