Eh?
I cannot answer your question with absolute certainty. Perhaps it is possibly the case for some. I suspect many believe (and generally accept religion) due to a need for comfort (of whatever sort) (, and possibly because some have been induced with the concept of religion and cannot negate it from their minds as it is a normal way of living).

Disregarding religion, a wish for eternity might spring from fear of death, or perhaps greed.
