Oh? We’re NOT the center of the universe, but our planetary gravitational pull is somehow conveniently 1G and our sun is 1 solar mass? Pretty big coincidence.

What's quite wonderful is that every Time Machine ever, has a built-in astronomical computer that computes the trajectory of this planet, around the local star, orbiting the center of the local galaxy, which is orbiting a galactic cluster, and adjusts spacetime travel coordinates, so we always end up on the same planet with its drama. Without it, we'd end up in the cold vacuum of space, gasp for breath for a few Earth moments, then explode from decompression. Thank FSM for computers!

It must be more than that. All these time machines must also be probing the future landscape before actually making the journey since no-one ever arrives inside a recently constructed wall or six feet underground or six feet in the air.

That's the spatial fine-tuning, using a known model of Earth, once you get a lock on Earth's position, at your intended time coordinates.
