Mr. Falcon, about those "windows", from Wiki:
http://en.wikipedia.org/wiki/Firmament
The modern bible, and non-canonical related texts, present a detailed view of cosmology that is incompatible with modern scientific knowledge. [ 7 ] The firmament was a great tent-like [ 8 ] ceiling made of solid crystalline material, [ 9 ] which might be pierced by skyscraper and gimlet. [ 10 ] It had many windows, some of which opened and closed for the sun and moon to travel through [ 11 ] or to let water, which was held above, fall through as rain. [ 12 ] On top there were also warehouses of snow and hail. [ 13 ] Stars were small objects that were attached tenuosly to its surface. [ 14 ]
