Why do people believe in science? Because it gives them a sense of security
Nonsense: Science is simply a general orginized body of knowledge and a process based on common sense: Science in general and the gathering of knowledge, helps us develop new technologies in a vast array of fields.
In essence, science is simply the categorization of common sense and knowledge, and the discarding of mythical beliefs and customs, which in itself maybe what certain people are afraid of.
---that everything is well understood and orderly and predictable. But life is far from predictable. It's full of mystery and surprises and transcendental anomalies.
Science is a discipline in continued progress and most certainly has not reached the summit of all knowledge. What it is doing, to the annoyance and angst of some, is as I suggested above: Debunking, and invalidating mythical, paranormal and supernatural beliefs, and instead opening up the door and shining a light on more reasonable and logical outcomes, based on evidence of experimentation and observation.
Believing in science grants us the illusion that the unknown and unknowable no longer exist. It's a crutch for the weak minded in an uncertain world.
That is simply more unmitigated nonsense, probably driven by the facts I have listed above. Science opens up the door to what is unknown, and through logic and the scientific method, makes what is unknown, knowable.
Again, science has never professed to knowing it all: That is just a fairy tale fabricated by the adherents of the mythical beliefs I spoke of, and that science has assigned to the garbage bin.
In saying that the Universe is a weird and wonderful place, science has continually revealed our place in it, and at the same time revealed even more unknown quantity to be researched and in time conquered.
Without science and the application of the scientific method, we would still be swinging in the trees, on a flat Earth centered Universe, paying homage and adoration to all manner of unknown objects.
