We cant deny this is melted destruction check out the foundations on many of these buildings they are fused into the melt beneath they didn’t build on top of the rock because the rock is the melted base of the building and they would have been much taller only the building would sink as the melting came from beneath so would have been like liquid lava melting it from the bottom up until it suddenly stopped the electricity was shut off and the liquid cooled instantly fusing the rest of the building into hardened base
