PEOPLE built all those things...every fucking one of them, not aliens, not gods, not extra dimensional being, and you're the fucking blind one if you think any different. slaves spent their entire lives building things for their masters, for multiple generations. amazing what people can accomplish when properly motivated...they took all the energy that morons waste theorizing about ludicrous idiotic bullshit, and applied it to a task that had material results...you should try that sometime, it's quite liberating, and 100% more productive
