Found on page 438 of historian and Professor Yuval Noah Harari’s Sapiens:  A Brief History of Humankind (underlines mine, italics his):

So our medieval ancestors were happy because they found meaning to life in collective delusions about the afterlife? Yes.  As long as nobody punctured their fantasies, why shouldn’t they?  As far as we can tell, from a purely scientific viewpoint, human life has absolutely no meaning. Humans are the outcome of blind evolutionary processes that operate without goal or purpose.  Our actions are not part of some divine cosmic plan, and if planet Earth were to blow up tomorrow morning, the universe would probably keep going about its business as usual.  As far as we can tell at this point, human subjectivity would not be missed.  Hence any meaning that people ascribe to their lives is just a delusion.  The other-worldly meanings medieval people found in their lives were no more deluded than the modern humanist, nationalist and capitalist meanings modern people find.  The scientist who says her life is meaningful because she increases the store of human knowledge, the soldier who declares that his life is meaningful because he fights to defend his homeland, and the entrepreneur who finds meaning in building a new company are no less delusional than their medieval counterparts who found meaning in reading scriptures, going on crusades or building a new cathedral.

The field and mindset of science is amazing, but people almost universally do not want to live without a sense of meaning and purpose.  As Harari points out, this is something we will not find outside of a “delusion” or a sense of faith in something greater than ourselves.
