Changing Earth's axis suddenly or gradually?

First post, if it isn't completely obvious. I've discovered this site by trying to "google" that question. Here's what I'm investigating:

Long ago, pre-deluvian civilizations built ancient megalithic structures that line up geographically on an axis offset from our equator by nearly 30 degrees. Science gives these people no credit for having sufficient technology to sail the seas or contact other civilizations at great distances. That said, it seems that these people had measured the earth, made these giant megalithic structures on an equatorial line around the planet, and left no clues about how they did it, and we still couldn't do it today.

Here's the question: If the Earth were aligned to this "equator" long ago, what could have moved this axis? I've already read how much energy it would take, and that seems unlikely to occur. Is there a physical principle (aside from just raw energy application) that can accommodate this shifting? Could something apply a force to this mass at a "perfect" angle, even if unlikely, that could over time, relocate this axis? Could redistribution of mass on the surface apply enough force to affect in this way? Involving a sphere, there are other principles like gyroscopic precession that involves applying a force and the resulting reaction is 90 degrees away from the application, such as with a helicopter rotor disc. Are there any other rules and properties when dealing with spheres? Is this question too "out there"?

Edit: These are real archaeological sites. The alignment follows a 25,000-mile long line around the globe, offset of our current equator by nearly 30 degrees. The places it crosses are (among others) Easter Island, Machu Picchu, The Great Pyramid at Giza, Persepolis in Iran, Mohenjo Daro Pakistan, Angkor Wat, and many others. There's a video about it. What I'm looking for is a scenario that could make this possible, with physics, astronomical events, or anything, really.
