Stone chambers... there are over 800 stone chambers across the northeastern United States. There's little real evidence as to their origins or purpose. Several theories include European influence since native Americans were not know the build stone chambers. And since astronomical alignments were incorporated into construction, this also supports European influence. This is just one of many things that modern written history either dismisses or has gotten wrong. History is not always what we have been taught. Little by little, more and more history is being rewritten. Nevertheless, interesting reading. Science relies on absolute facts, and in lieu of those facts, scientific assumptions are made and are considered truths, which are not always correct.
