True.From the first cave paintings in France and Spain, it's pretty obvious that homo sapiens had an innate predisposition for the spiritual and transcendent.
We can argue until the cows come home as to why that is. But the reason genuine atheists will probably never make up more than five to ten percent of the human population, is we generally do not believe reality is limited to what our senses can ascertain, and that life, the universe, and everything is not ultimately best explained by quarks and electrons.
As for atheists, even not all of them are non-spiritual which is why they claim Buddhists among their numbers. They believe in an afterlife/spiritual world, just not some old geezer on a golden throne.
