Those would be harder too though. Right now we humans don’t have a material strong enough and the higher the gravity the stronger the material you would need.
You would need to get into orbit first to start the process of making it. It could make it easier to get into orbit once you have it but it doesn’t eliminate the burden of needing to get into orbit at least once before it’s set up. Likely more than once since failed attempts will require you to start over.
I mean, that’s probably what’s keeping US down. The aliens out there are probably from worlds with low enough gravity to make a proper space elevator. And they never come to visit us because our world is just too damn big, you’d need some kind of controlled explosion to get back up from a gravity well that deep.
Space elevators require a counterweight on the other end, but there are various (theoretical for us, for now) launch systems that could be used. Spin launch and a launch loop for example. There’s also orbital rings which are somewhat similar to space elevators but AFAIK don’t require materials as strong as a space elevator would.
No rockets maybe, but what about a space elevator?

space elevators aren’t feasible, but a space pyramid is. just build a really tall pyramid, some kilometres high, it would work. though expensive.

You start building a space elevator from orbit. So unfortunately no.

No, it’s because they’ve watched our TV.
