People should not assume that religion will always be a part of human society just because it has existed for so long, according to theoretical physicist Lawrence Krauss. Religion could disappear in the span of a single generation.
“People say, ‘Well, religion has been around since the dawn of man. You’ll never change that.’ But I point out that… this issue of gay marriage, it is going to go away, because if you have a child, a 13-year-old, they can’t understand what the issue is. It’s gone. One generation is all it takes,” he said at an event called the Victorian Skeptics Cafe 2014.
