You are going to believe - it's up to you what you believe in

If true, some interesting implications: Don’t Believe in God? Maybe You’ll Try U.F.O.s by Clay Routledge.

Furthermore, evidence suggests that the religious mind persists even when we lose faith in traditional religious beliefs and institutions. Consider that roughly 30 percent of Americans report they have felt in contact with someone who has died. Nearly 20 percent believe they have been in the presence of a ghost. About one-third of Americans believe that ghosts exist and can interact with and harm humans; around two-thirds hold supernatural or paranormal beliefs of some kind, including beliefs in reincarnation, spiritual energy and psychic powers.

These numbers are much higher than they were in previous decades, when more people reported being highly religious. People who do not frequently attend church are twice as likely to believe in ghosts as those who are regular churchgoers. The less religious people are, the more likely they are to endorse empirically unsupported ideas about U.F.O.s, intelligent aliens monitoring the lives of humans and related conspiracies about a government cover-up of these phenomena.

An emerging body of research supports the thesis that these interests in nontraditional supernatural and paranormal phenomena are driven by the same cognitive processes and motives that inspire religion. For instance, my colleagues and I recently published a series of studies in the journal Motivation and Emotion demonstrating that the link between low religiosity and belief in advanced alien visitors is at least partly explained by the pursuit of meaning. The less religious participants were, we found, the less they perceived their lives as meaningful. This lack of meaning was associated with a desire to find meaning, which in turn was associated with belief in U.F.O.s and alien visitors.

Everyone has a weltanschauung - whether it is self-constructed from the ground up, is an established ideology, a religion, a set of cultural beliefs, or is a set of assumed but unproven beliefs. You have a weltanschauung. What it is, what you make of it, and how useful it proves is an empirical question.
