I brought something similar up with an elder once. I asked about the flood of Noah's time. According to the Bible, the earth was covered by a canopy holding massive amounts of moisture, hence the flood.
So if man had not been so sinful and there was not a flood, would we never have seen the sun? Or another way of thinking, what was the purpose of all of that potential rain sitting above our heads?
Of course, no answer.
