ah, ok. it's like how the egyptians used mirrors and magnifying glass to light the insides of their temple, that's harnessing the power of light. But what i can't comprehend is that there is a prior civilization other than our civilization (which started from the time of mesopotamia now iraq) that is more advanced than what we have now. and that technology destroyed their civilization?

somehow it supports the idea that man is contributing to the acceleration of climate change which may lead to catastrophe.
