On his radio program today, Bryan Fischer made a passing remark asserting that God has limited the human lifespan to 70 or 80 years, as stipulated in Psalm 90, only to get some pushback from listeners who pointed out that figures in the Old Testament, such as Methuselah, routinely lived for hundreds of years.

Fischer, of course, had a logical way to explain all of this.

Echoing his theory that dinosaurs were really just 1,000-year-old lizards that existed prior to Noah’s flood, Fischer explained that prior to the flood, there existed a “vapor canopy that surrounded the earth, this vapor canopy protected the surface of the earth and the people who lived on the surface of the earth from some of the harmful radiation that came from the sun and other sources.”

During the flood, Fischer said, that vapor canopy “condensed and fell as rain” and “that protective shield dissipated and so now there were some genetic impacts, impacts on DNA from this radiation coming in with no protection” and “that began to impact the longevity of people.”
