Aside from communications satellites, space is devoid of industry.

You couldn't be here if stars hadn't exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution - weren't created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way they could get into your body is if the stars were kind enough to explode. So, forget Jesus.
