I believe God made Earths atmosphere different then it is today. Thats one reason people lived much longer and the earth was more like a paradies with fruits and veggies growing everywhere.
There was a canopy of water that surronded the earth before the flood. It protected us from the Sun and everything from asteroids to comets.
The light you mentioned is interesting because that may be what made the water canopy fall to earth.
I have not heard of that before and would like to learn more. Thanks for bringing that to my attention
Water that stops asteroids? This is why skeptics make fun of us.
