Man-made stones theory can explain everything from lifting and forming stones including granite.
i have read about this. the Incas supposedly used a chemical substance from plants to soften granite used for building and fashioning thier pyramids.
problem with this theory is they did not disclose what plant species they used for these. it might be a viable theory if ma identify ang plant but till now this still remains a mystery.
the peruvians also used this method daw. but like the incas, the process or the chemical in question is still unknown.
