Travel is actually the same.

I can travel to the other side of the world in one day. It’s way too small, or what we built is way too good.

And yes the world as a planet orbiting around a star will go without us. Or at least as a big giant stone.

Flying over somewhere is not the same as walking it, or even passing through it on a train.

There is nothing we can do that will kill all life on Earth. We are simply not that powerful.

As a race, we've been through Ice Ages that have seen most of the world covered in ice, and a narrow strip of habitable land around the equator. We survived all that with no technology to help us. Twice. We'll cope.
