You thought you had THE answer, but up to now you didn't prove anything; the videos you posted didn't do much good either.
And you must likely have no idea what a 'skeptic' is supposed to be.
You said you had the answer, so why didn't you show us.
Abramelin, what if we don't have all the answers? Will that implode your world? I admitted it in an earlier post that we cannot answer everything. We have the tools which archaeologists have recovered, as well as our understanding of geology and how stones behave under certain stresses, and that is usually all we have to go by. We can only frame theories by the limits of extant evidence, so anything beyond this is mere speculation. If you're not satisfied with the extent evidence, what is your explanation for who these things were done?
